For some time now, linguists and language learners around the world have argued that English is one of, if not the hardest language to learn. But is English the hardest language to learn? Aside from the fact that many of the words in the English language stem from Ancient Greek and Latin, English also has some pretty complex grammatical, spoken, and written rules 鈥 which even native speakers often get confused with! But is English a hard language to learn for non-native speakers, or does its global presence make it easier to pick up? If the English language really is as challenging as many perceive it to be, why do so many people speak it? English is the most widely spoken language in the world, with over 1 billion people.

Why English can be hard to learn

It鈥檚 widely accepted that English is hard to learn - if not the most difficult language to learn. Let鈥檚 take a look at some of the most common reasons why people find it so challenging.

There are lots of rules

In the English language, as with many other languages, there are a lot of rules for new speakers to learn. And these rules aren鈥檛 just applied to one area of the language either; from grammatical rules to learning how to spell longer words, there are a lot for you to try and learn.

But, and perhaps, most confusingly, these rules often get changed, refuted, or can just simply be 鈥榳rong,鈥 depending on the word or phrase you鈥檙e trying to say or spell.

For example, one of the most confusing yet widely used rules in the English language is: 鈥業鈥 before 鈥楨,鈥 except after 鈥楥.鈥

When it comes to spelling lots of words, such as 鈥榝riend,鈥 鈥榖elieve, 鈥榬eceive鈥 and 鈥榗onceive,鈥 the rule stands true. However, there are many exceptions where the rulebook is thrown out the window, such as 鈥榮cience,鈥 鈥榓chieve,鈥 and 鈥榳eird.鈥

Yet, the confusion doesn鈥檛 stop there. When it comes to the construction of sentences or even which nouns, verbs, objects and pronouns to use, there are several confusing rules to understand.

One rule that鈥檚 embedded into students early-on in their English learning is the 鈥楳e vs. I鈥 rule, which states that you should use the pronoun "I" in sentences when the person speaking is doing the action, either alone or with someone else. But, you should use the pronoun "me" when the person speaking is receiving the action of the verb in some way, either directly or indirectly.

For example, it is correct to say 鈥淛ane and I went to the theatre.鈥 But in some sentences, you should use the pronoun 鈥榤e,鈥 such as in; 鈥淢y Mum met me and my Dad at the theatre.鈥 It鈥檚 all about taking out the other person and seeing if 鈥榤e鈥 or 鈥業鈥 sounds the most logical. 鈥淛ane and me went to the theatre,鈥 for instance, sounds incorrect and should not be used.

Native speakers have an intuition of which words to select, based on how they sound. For those trying to learn the language, getting used to all the complexities and exceptions to the rules can be really challenging if you don鈥檛 have this basic intuition to draw on.

And writing rules are on a whole other level

Written English is often considered the most difficult element - even native English speakers make mistakes within their writing, especially when it comes to punctuation.

There are so many different grammatical structures and rules that need to be followed when writing. From applying to the Oxford Comma in lists to using conjunctions to link ideas together in sentences, there are a whole variety of rules for new speakers to acquaint themselves with.

One of the strangest written rules is the capitalisation of the English pronoun, 鈥業.鈥 When we examine different English pronouns, including 鈥榤e,鈥 鈥榶ou,鈥 鈥榯hey,鈥 鈥榮he鈥 and 鈥榯hey,鈥 it is only the pronoun 鈥業,鈥 which is written in capital letters, regardless of its form. Why? Well, no one really knows.

English vocabulary has mixed origins

Another interesting reason why English is hard to learn is that it has very mixed origins, with its roots found in different languages.

More specifically, the language is part of the Indo-European language family, establishing its foundations from German, Latin and French, but with languages like Persian, Hindi and Russian having an impact too. In fact, an estimated 29% of the English language is French, 29% Latin, and 26% has Germanic roots. The remaining 10% comes from all the other languages.

This can make it easier for French, German or Latin speakers, as they are already familiar with much of the vocabulary. But for new learners who do not have that jump-start, trying to learn a language which combines several others can be extremely challenging. Especially when trying to take rules and spellings you鈥檙e already familiar with, and applying them to new words and phrases which don鈥檛 even follow the same rules.

Idioms can make language learning confusing

Now, idioms can be found in every language around the world. They鈥檙e small, quirky sayings that aren鈥檛 meant to be taken literally, but are commonly used within a particular language to describe a characteristic act, process or expression.

In the English language, some of the most common - and most unique - idioms include:

  • 鈥淗it the hay鈥 - to mean you are going to go to sleep
  • 鈥淭hey hit the roof鈥 - to describe someone as being very angry
  • 鈥淎ll of a sudden鈥 - to mean something happened quickly
  • 鈥淚t鈥檚 a piece of cake鈥 - to refer to something as easy
  • 鈥淚t鈥檚 raining cats and dogs鈥 - meaning that it鈥檚 raining hard
  • 鈥淐osts an arm and a leg鈥 - something that costs a lot of money
  • 鈥淯p in the air鈥 - to speak about uncertainty, no conclusive decision
  • 鈥淏reak a leg鈥 - a way of wishing someone good luck

There are tens of thousands of idioms in the English language, and many of which can be regional - that is, only the people that live locally know and use them.

Understandably, when a new language learner hears a phrase such as 鈥渂reak a leg,鈥 they may be rather perplexed by what you mean. Idioms are nonsensical, confusing, and unpredictable in what they refer to.

But for anyone learning English who plans on immersing themselves in British culture, learning idioms is a crucial element. Many common conversational idioms are used by native speakers, so you need to be familiar with them if you are to be able to hold a conversation.

There are so many tenses, and all mean something slightly different

Another common complaint surrounding the learning of the English language is the tenses. Tenses - whether spoken or written - can completely change the meaning of a sentence. And in English, there are lots of different tenses which can mean different things.

Before we get into the complexities of the tenses themselves, we should explain how there is a lot of argument around how many tenses there even are. Some experts argue that there are thirteen, while others claim it to be sixteen. And the very fact that we are unable to agree on a particular amount demonstrates the very difficulty of them.

Now we鈥檝e established their complexities, let鈥檚 take a deeper look at the challenges that come with understanding each different tense.

First, learners need to look at the time frame of the tense:

  • Past: It has already happened
  • Present: It is happening now
  • Future: It is going to happen

Seems simple enough, right? We either speak about an event in the past, present, or future. That鈥檚 like most languages in the world. Just wait.

Once we鈥檝e established the time frame of the event, these three frames are then divided into three further sections to tell us how to look at an event or action:

Past tenses:

  • Past-simple: I ran
  • Past-continuous: I was running
  • Past-perfect: I had ran

Present tenses:

  • Present-simple: I run
  • Present-continuous: I am running
  • Present-perfect: I have ran

Future tenses:

  • Future-simple: I will run
  • Future-continuous: I will be running
  • Future-perfect: I will have ran

These tenses are all so closely related, and yet have the ability to completely change the meaning of a sentence or the way we understand it.

With so many different tenses to understand, it鈥檚 no wonder that so many find English hard to learn or often find it difficult to maintain the same tense when speaking or writing. Many native speakers often find themselves shifting tenses unknowingly, showing just how difficult it can be to maintain consistency.

The rules around plurals aren鈥檛 always synonymous

Now, if you thought that the rules around tenses were confusing, you鈥檙e about to discover a whole new level of confusion as we explore the rather perplexing rules around plurals.

In most cases, singular nouns are usually made plural by simply adding an -s on the end. But, there are cases where pluralisation rules change depending on what letter a noun ends in.

For example, if the noun ends in 鈥憇, -ss, -sh, -ch, -x, or -z, then you are required to add 鈥慹s to the end to make it plural. E.g. 鈥榖us鈥 becomes 鈥榖uses,鈥 and 鈥榯ax鈥 becomes 鈥榯axes.鈥

But, if the noun ends with the letter 鈥慺 or 鈥慺e, the f is often changed to 鈥憊e before adding the -s to form the plural version. E.g. 鈥榳ife鈥 becomes 鈥榳ives鈥 and 鈥榮helf鈥 becomes 鈥榮helves.鈥

To make matters even more confusing, there are some exceptions to the rule. For example the singular 鈥榗hef,鈥 becomes a plural 鈥榗hefs,鈥 while your single 鈥榬oof鈥 will become multiple 鈥榬oofs.鈥

These are just a couple of examples of the rules that exist around plurals in the English language. There are many more plural rules that language learners need to make themselves aware of, which are often illogical, irregular, or just outright confusing.

Pronunciation is difficult

As if the rules around written English weren鈥檛 difficult enough to understand, the way we pronounce words when speaking also causes much difficulty for those trying to understand and use the English language.

Firstly, many words in the English language are spelt with letters at the beginning of them which are silent when pronounced, such as:

  • 鈥淜nife鈥 - is pronounced 鈥榥ife鈥
  • 鈥淢nemonic鈥 - 鈥榥ew-mon-ic鈥
  • 鈥淧neumonia鈥 - 鈥榥ew-moan-ee-a鈥
  • 鈥淕nash鈥 - 鈥榥ash鈥

When not pronounced, this makes spellings of the words with silent letters very difficult for new language learners to write down - as they often turn to phonetics to make spelling words that bit easier.

And secondly, and even more confusingly, when spoken aloud, many words that end in the same letters aren鈥檛 always pronounced in the same way. For example:

  • 鈥淐ough鈥 - is pronounced 鈥榗off鈥
  • 鈥淩ough鈥 - 鈥榬uff鈥
  • 鈥淭hrough鈥 - 鈥榯hroo鈥
  • 鈥淎lthough鈥 - 鈥榓ll-tho鈥
  • 鈥淏orough鈥 - 鈥榖u-ra鈥

Unfortunately there鈥檚 no common rule set that can be applied to the pronunciation of words. Much of the learning has to come through practice either speaking or listening to the words, which can be quite frustrating for new learners.

You can鈥檛 use synonyms interchangeably

When learning English, you鈥檒l probably look in a thesaurus and discover that there are several groups of words that generally mean the same thing - these are referred to as 鈥榮ynonyms.鈥

Now, if these words all generally mean the same thing, it鈥檚 easy to understand why many English language learners assume that you can use them interchangeably. But you can鈥檛.

English words have various definitions. Even those which share a similar meaning can refer to something completely different. And because of this, many learners end up misusing words.

For example, in common conversation you may say that you want to 鈥渟ee a movie,鈥 or even 鈥渨atch鈥 it on television. But, it would be wrong to say that you would 鈥渟ee a television.鈥 Similarly, when you 鈥渨ant鈥 to purchase a new pair of jeans, you would never say 鈥淚 desire a new pair of jeans.鈥 It just doesn鈥檛 make sense in spoken English.

Even if the two words share very similar meanings, you should take a look at the context around them as they could be completely different from one another. Again, it鈥檚 something that comes with practice and intuition from speaking to locals.

Essentially, the English language can be nonsensical

Finally, and perhaps something you鈥檝e picked up on while reading this article, the English language is often full of inconsistencies and illogical pairings that means reading, speaking, and listening the language is confusing to non-native speakers.

For example, take the word 鈥榮trawberry.鈥 Now, what does the word 鈥榮traw鈥 have anything to do with the red juicy berry fruit? Sometimes, the pairings just seem illogical.

And it鈥檚 not just words either. Often there are cases where nouns may become verbs, but the rules change depending on the word. For example, teachers will have 鈥榯aught鈥 their students, whereas preachers will have 鈥榩reached.鈥

Add to this different regional dialects adding different pronunciations and even idioms to the English language, and you can understand why so many inconsistencies have come to be common practice in the English language.

These inconsistencies can make it really difficult for learners to understand and adopt rules of the language. You have to learn the commonalities of the way people speak, rather than learning one simple rule.

Is English the hardest language to learn?

Throughout this article, we鈥檝e demonstrated how challenging the English language can be for new learners. With its vast amount of rules, complex origins and illogical language patterns, it鈥檚 no wonder that so many learners complain of its difficulty.

But when you compare English against other challenging languages, such as Mandarin, Arabic or Japanese, its difficulty is often debated. Mandarin, for example, is known for having a famously-difficult emphasis pattern of speaking, which can change entire sentences and meanings based on the tone a person uses. Meanwhile, written Arabic has a different script for each variation of a letter, depending on where in the word it sits.

These different challenges mean the perceived difficulty of each of these languages ultimately comes down to the learner. It鈥檚 what is relatable to what you already know. E.g. If your native tongue is one of the languages which has its roots firmly in the English language, such as French or German, you may find it easier to learn compared to someone from a country which has no origins in the English language.

Likewise, if you are native in a language which uses symbols in written language, such as Japanese, then you鈥檒l find it much easier to understand than someone who doesn鈥檛. It鈥檚 all about the general understanding we have of our own language, and how we use this to translate and decode those which are similar or different from what we know.
