Common Mistakes A common mistake is to forget to put the -s ending

on the he/she/it forms.

All verbs except modals must end in -s in the third person singular affirmative:

wrong: Our new computer system work very efficiently.

right: Our new computer system works very efficiently.

Common Mistakes

A second common mistake is to add the -s to the he/she/it forms of negatives and questions.

We add the -es form to the auxiliary (do), and not to the main verb (work):

wrong: I know Kari doesn’t works in Accounts.right: I know Kari doesn't work in Accounts
