IELTS Spelling · Plurals
Plurals in IELTS Listening
One letter. A sentence completion where the answer should be tickets and you wrote ticket scores nothing, and it is the kind of mark that is infuriating afterwards because you clearly heard it.
The short answer
Two different things go wrong with plurals, and they need two different fixes. One is hearing the s at the end of a word. The other is reading the sentence you are completing, because the gap has to fit the grammar around it. The second is the bigger earner.
Let the sentence tell you
In sentence and note completion, the words on either side of the gap usually settle the number before you hear anything:
- The centre has three …… — after three, the answer is plural whatever you heard.
- Each student must bring a …… — after a, it is singular.
- The …… are open at weekends — are demands a plural subject.
Reading the gap in its sentence before the recording reaches it is the single most useful habit in the Listening test, and the plural question is where it pays most obviously.
Hearing the ending
The plural ending is pronounced three ways, and only one of them is a clear s:
- /s/ after most unvoiced sounds: books, maps, cats.
- /z/ after most voiced sounds: bags, cars, rooms — it sounds like a z and is still written s.
- /ɪz/, a whole extra syllable, after s, z, ch, sh, x: buses, watches, boxes — written -es.
The spelling changes
- -y becomes -ies after a consonant: library → libraries, country → countries. After a vowel it does not: days, keys.
- -f and -fe become -ves in many words: shelf → shelves, knife → knives, life → lives.
- -o is inconsistent: potatoes and tomatoes, but photos and pianos.
Irregular plurals worth owning
child → children, woman → women, man → men, foot → feet, tooth → teeth, person → people, criterion → criteria, analysis → analyses, medium → media.
Note that women changes its spelling but barely its sound in some accents — it is a word to practise by typing, not by listening alone.
Words that look plural and are not
Do not strip the s off these: series, species, news, means, mathematics, economics, physics. One series, two series.
And do not add one to these, which have no plural at all: equipment, information, advice, luggage, furniture, accommodation, research, homework, money. If the sentence seems to want informations, you have misread the gap.
Practise these
Dictation catches the ending you cannot hear and the ending you can hear but do not type. The letter-by-letter check makes a missing s impossible to miss afterwards.
Practise plurals by dictation
The Spelling trainer says a word once, in the accent you pick, and checks what you typed letter by letter — then gives you back only the words you missed.

Questions people ask
If I am not sure, should I add an s?
Do not guess from the sound. Read the sentence around the gap: an article, a number or the verb will usually decide it, and that evidence is on the screen in front of you rather than gone with the audio.
Is equipments ever right?
No. Equipment is uncountable, like information, advice and luggage. If a sentence seems to need a plural there, something else about the gap is being misread.
Does a missing s really cost the whole mark?
Yes. A word with a spelling error in Listening or Reading is marked incorrect, and a singular where the sentence needs a plural is exactly that.
The other five groups
- Numbers and dates — Phone numbers, prices, times, reference codes and the date — the Part 1 answers that are lost to a digit, not to English.
- Days and months — Wednesday, February, Tuesday and Thursday — twelve words and seven words, and a surprising number of lost marks.
- Place names — Street, Road, Avenue, and the town name the speaker spells out letter by letter at exactly the wrong moment.
- Personal names — Surnames spelled aloud, hyphens, apostrophes, and the letters that sound the same at speed.
- Double letters — Accommodation, necessary, committee, occurred — the words where the only question is how many of each letter.
And the whole picture, with the marking rule and the accents, is on the Spelling trainer page. The words themselves come out of the Listening tests, which run in the computer-delivered interface here.
The marking rule — "words with spelling errors in the Reading and Listening tests will be marked as incorrect" — is IDP’s own wording on How to improve your spelling and Common spelling mistakes, both checked 2 October 2026; the same pages say British and American spellings are both accepted as long as you stay consistent. "You will hear the recordings once only" is from the official IELTS Listening format page, checked 2 October 2026. The two minutes to check at the end of the computer-delivered test, and the fact that the screen has no spell-check, are per the British Council’s paper versus computer guidance, checked 2 October 2026. The six groups of words below are how this trainer organises practice, not an official list. IELTS Computer is not affiliated with IDP, British Council or Cambridge.
