Table with Common English Irregular Plural Forms
The English language is known for its exceptions and special cases, and irregular plural forms are a prime example. Some of the most common irregular plurals are child – children, man – men, and woman – women. These words can be especially hard to remember because they don’t follow the regular plural rule of simply adding an “s.” Instead, they often change their vowel or take on a completely different form, making them particularly challenging for some language learners to master.
Here is a table with the most important irregular plural forms:
Singular 🇬🇧 | Plural 🇬🇧 |
---|---|
Child | Children |
Foot | Feet |
Goose | Geese |
Leaf | Leaves |
Life | Lives |
Man | Men |
Mouse | Mice |
Person | People* |
Tooth | Teeth |
Woman | Women |
*“People” is the standard plural of “person” and is used almost always.
👉 There are many people at the party.
*“Persons” can also be used but only in formal or legal contexts.
👉 Missing persons report
👉 Authorised persons only

Rules and Exceptions for Irregular Plural Forms
The rules for irregular plural forms in English aren’t always easy to figure out. While most nouns simply form the plural by adding an “s,” there is no single rule for irregular forms. Instead, these plurals are often based on historical or linguistic peculiarities. However, having a basic understanding of these exceptions can help you use the plural forms correctly.
English also has many words with silent letters. I’ve written an article and created a video course about that as well:

A typical example of a rule that is often broken is the vowel change in the word stem, as seen in man – men or woman – women. These changes are historically based and come from older versions of the English language. Another common pattern is the change of the final letter, as with leaf – leaves or life – lives. In this cases, the ending “f” changes to “ves” in the plural version.
Despite these rules, there are also words that seem to defy any logic. One example is sheep, which remains the same in both singular and plural. Such words are especially challenging because they don’t undergo any visible change and can only be used correctly through context or experience. These exceptions require a certain amount of memorisation and practice to master them properly in everyday language. For some types of learners, I would also recommend writing them down. For this, I’d recommend these* vocabulary flashcards.
Tips for Using Irregular Plural Forms Correctly
Irregular plural forms can be a stumbling block even for advanced English learners. A key tip for dealing with them is to regularly read and listen to English texts where these forms appear. This helps you internalize the correct usage in a natural context. Reading books, newspapers, or listening to podcasts and watching movies in English can help you learn irregular plural forms in an intuitive way. You can check out the 20 best series for learning English right here.
Another effective method is keeping a vocabulary notebook* where you write down the irregular plural forms you come across. Update this list regularly and try to use the words in your own sentences. Actively writing and speaking with these words strengthens your understanding and helps you recall the correct forms more quickly.
Finally, using exercises and quizzes is a great way to test and deepen your knowledge. There are many online platforms and apps specifically designed to help you learn irregular plural forms. Use these resources to regularly review and expand your knowledge. This way, you’ll gradually internalize the exceptions and be able to use them confidently in conversation. I highly recommend Preply* for this purpose.
How to Learn Irregular Plural Forms
To learn irregular plural forms effectively, targeted practice is essential. That’s why I’ve included the video and flashcards in this article. I recommend watching the video several times and to use the flashcards above. For some learning types, it also makes sense to write them down again in a vocabulary notebook or on flashcards. You can find these and other helpful products right here.
Another useful exercise format is multiple-choice questions that require you to choose between several possible plural forms. These exercises challenge you to recall your knowledge and check whether you can correctly identify the irregular forms. This type of question can also be used in group or partner activities to encourage interactive learning.
Finally, writing exercises can also help solidify what you’ve learned. Try writing short stories or dialogues where you deliberately use irregular plural forms. Writing forces you to actively apply the forms and get creative with the language. By practising regularly in different formats, using irregular plural forms correctly becomes a habit and greatly boosts your language confidence.
These kinds of exercises can be done with an AI – here’s an example. However, I would still recommend private lessons with an expert, for instance on Preply.
