Present Simple: Affirmative and the -s Ending

Cover: Present Simple affirmative — add -s for he, she, it, with examples: I work, she works, he goes, she studies
Short answer

In the present simple affirmative you use the base verb for I, you, we and they, and add -s (or -es/-ies) for he, she and it: 'I work' but 'She works'. Use it for habits, routines, general facts and timetables.

Level: A1. The present simple is the tense you use for things that are generally true — habits, routines and facts. In the affirmative it is almost the base verb unchanged; the one thing to master is the -s that appears with he, she and it.

The rule

A verb is a word for an action or state (work, live, have). The present simple describes what happens regularly or is always true, rather than what is happening right now.

The form is simple: for I, you, we and they you use the plain base verb. For the third person singular — he, she, it, or any single person or thing — you add -s to the verb:

  • I work. / They work. → He works. / She works.
  • We live here. → It lives here.

That final -s is the whole trick of the affirmative present simple. Dropping it (“he work”) is the single most common beginner mistake in English.

Spelling of the -s ending

Verb ends in… Add Example
most sounds -s work → works, play → plays, live → lives
-s, -ss, -sh, -ch, -x, -z, -o -es go → goes, watch → watches, fix → fixes, kiss → kisses
consonant + y -ies study → studies, carry → carries
vowel + y -s play → plays, buy → buys
irregular — have → has, be → is

So the ending you write depends on the last letters of the verb — but it only ever changes in the he / she / it form.

How to say it

The written -s has three different sounds. English learners often add the wrong one, so match the sound before it:

After this sound Say the -s as Examples
a voiceless sound (p, t, k, f) /s/ works, sleeps, eats
a voiced sound (b, d, g, l, vowels) /z/ lives, plays, runs, goes
a hissing sound (s, z, sh, ch, x) an extra syllable /ɪz/ watches, washes, fixes

The verbs goes and does are also pronounced with a changed vowel: goes rhymes with “nose”, and does sounds like “duz”, not “dooz”.

Example sentences

  1. I work in an office.
    Base verb with 'I' — no -s.
  2. She works in a hospital.
    Add -s for 'she'.
  3. They live in London.
    Plural subject — base verb.
  4. He lives in Paris.
    'He' takes -s.
  5. We play football on Sundays.
    A regular habit.
  6. The sun rises in the east.
    A general truth.
  7. Water boils at 100 degrees Celsius.
    A scientific fact.
  8. My father watches the news every evening.
    -es after -ch.
  9. She studies Chinese.
    consonant + y becomes -ies.
  10. The shop opens at nine.
    A fixed timetable.
  11. He goes to work by train.
    Irregular -es spelling: goes.
  12. I drink coffee every morning.
    A daily habit.
  13. The baby cries at night.
    cry becomes cries.
  14. My brother and I speak two languages.
    Compound subject = plural, base verb.
  15. The train leaves at six o'clock.
    A scheduled event.
  16. She has a big family.
    Irregular: have becomes has.
  17. He does his homework after dinner.
    Irregular -es: does.
  18. Cats sleep a lot.
    A general fact about a group.

Common mistakes

  • ❌ He go to school. → ✅ He goes to school. Add -s (here -es) for he / she / it.
  • ❌ She study English. → ✅ She studies English. Consonant + y becomes -ies.
  • ❌ He haves a car. → ✅ He has a car. Have is irregular: he/she/it → has.
  • ❌ I works here. → ✅ I work here. Only he / she / it take -s, never I / you / we / they.
  • ❌ She watchs TV. → ✅ She watches TV. After -ch you add -es, not just -s.

A short conversation

A: What does your sister do? B: She works in a bank and studies at night. A: And you? B: I work from home. We both start early.

Usage notes

  • Habit vs now. The present simple is for routines, not the moment of speaking. “I work in a bank” (my job) is different from “I am working right now” (this minute).
  • Adverbs of frequency. Words like always, usually, often, sometimes, never go before the main verb: She always takes the bus — and the verb still keeps its -s.
  • Only the verb changes, once. In a present-simple affirmative sentence the -s appears on the main verb and nowhere else; there is no helping word.

Compared with…

  • Present continuous describes what is happening now and uses am/is/are + verb-ing: She is working today (this moment) versus She works on Mondays (a routine). See Present Continuous. For the helping verb to be that it uses, revisit Verb ‘To Be’ in the Present.
