Key Rules & Conventions
Modal + Base Verb Rule
Modal verbs are always followed by the base form of another verb.
After a modal verb (like can, must, should), the main verb never changes its ending. It stays in its simplest form, without -s, -ed, or -ing.
No -s for Third Person Singular Rule
Modal verbs do not change form for third person singular subjects (he, she, it).
Unlike most verbs, modal verbs do not add an '-s' when the subject is he, she, or it. The modal verb stays the same for all subjects.
No 'to' After Modal Rule
Do not use 'to' directly after a modal verb.
Modal verbs are strong helper verbs and do not need 'to' before the main verb. The structure is always modal verb + base form verb.
