WordsWhat you are actually practicing
English plurals look regular until they are not. Most words just add -s, but a large and frequently used group does something else: child becomes children, knife becomes knives, city becomes cities, and a few — sheep, fish — do not change at all.
This game is built almost entirely from the irregular group, because that is where mistakes actually happen. The regular -s rule is already known; the exceptions are what need drilling.
How the game works
You are given a singular word and must pick its plural from four options. Four choices, a countdown, and an immediate reveal when you miss. Your score and best score stay in this browser only.
Easy uses the most familiar irregulars. Medium widens the pool. Hard includes the words that do not change at all, where the correct plural looks identical to the singular and therefore feels like a trick.
The patterns worth knowing
Vowel changes: man → men, woman → women, foot → feet, tooth → teeth, goose → geese, mouse → mice.
-f or -fe becomes -ves: knife → knives, wolf → wolves, leaf → leaves.
Consonant plus -y becomes -ies: city → cities, baby → babies.
-s, -x, -ch, -sh take -es: box → boxes, bus → buses, dish → dishes, church → churches.
Some take -oes: potato → potatoes, hero → heroes.
Some never change: sheep → sheep, fish → fish.
Strategies that actually move your score
Say the word aloud. Many irregular plurals sound right once spoken, because the vowel change is phonetic: feet sounds plural in a way foots does not.
Check the ending letter. If the word ends in f, fe, y, s, x, ch, or sh, the regular -s rule probably does not apply.
Watch for the unchanged words. If one option is identical to the prompt, it may well be correct rather than a mistake.
Common mistakes, and the fix for each
Mistake: applying -s everywhere. childs and mans are the classic errors. The fix is to test whether the word belongs to one of the pattern groups above.
Mistake: writing -ies after a vowel. boy becomes boys, not boies. The -ies rule only applies after a consonant.
Mistake: assuming the identical option is wrong. For sheep and fish it is right. The fix is to know the small unchanged list by heart.
A short, honest FAQ
Do I need to install anything? No. It runs in any modern browser.
Why so many irregulars? Because the regular rule is already automatic for most players; the irregulars are where points are actually lost.
What age is it for? Roughly grades 2 and up, or any learner of English.
