Learn French: Je mets mon sac sur la chaise et j'écris. - I put my bag on the chair and I write.

Mettre (to put) is an irregular verb. To conjugate it for singular pronouns, you drop the entire -tre ending to leave the base met-, then add -s, -s, or nothing. This gives us je mets, tu mets, and il/elle met.

Why is there an apostrophe in j'écris but not in je mets?

Écrire starts with a vowel, so the e in je is dropped and replaced with an apostrophe to make the pronunciation smoother. This is a mandatory rule called elision. Because mets starts with a consonant, je stays as a separate word.

Is écris conjugated like regular -re verbs?

No, écrire (to write) is also irregular! For singular pronouns, it looks fairly normal: you drop the -re to get the base écri- and add -s, -s, -t (j'écris, tu écris, il/elle écrit). But for plural pronouns, a -v- appears before the endings: nous écrivons, vous écrivez, ils/elles écrivent.

Would a female speaker still say mon sac instead of ma sac?
