Tricky Plural Spelling

Welcome to the A2–B1 spelling test on tricky English plurals. Most English plurals just add "-s" to the end of the word — but a small group breaks the rule, and those are the ones learners get wrong again and again.

You'll practise 22 plural forms covering every major irregular pattern:

• Fully irregular: children, men, women, people, feet, teeth, mice
• -f / -fe changes to -ves: leaves, knives, lives, wives, shelves, wolves
• -y changes to -ies: babies, cities, countries, families, stories
• -o adds -es: potatoes, tomatoes
• Same form, singular and plural: sheep, fish

Each word comes with a short definition and clear audio. Listen, type the plural form, and get instant feedback on your spelling. The retry button takes you back through any words you missed until you get them all right.

Why these plurals matter

Writing childs instead of children, foots instead of feet, or mouses instead of mice is one of the most common beginner mistakes in English. These plurals appear in everyday conversation, text messages, and school writing — so getting them right makes a real difference to how confident your English sounds. Once you know these 22 words, the rest of English plurals follow simple rules that are much easier to remember.
