Every English verb has a small set of forms, and each one has specific jobs — including some surprising double duty.
What you'll learn
Every English verb has up to five forms: the base form, the -s form, the -ing form, the past form, and the past participle. Regular verbs often reuse the same form for the past and the past participle (worked/worked), but irregular verbs frequently don't (went/gone).
The -ing form does double duty. It's part of the continuous tenses (be + -ing): 'I am working.' But the exact same form can also act as a noun, called a gerund, as the subject or object of a sentence: 'Working from home has its perks.'
The past participle appears after have/has/had in the perfect tenses, and after be in the passive voice — two very different grammatical structures using the exact same verb form.
The present perfect needs the past participle (gone), not the past simple form (went) — these differ for many irregular verbs.
The continuous tenses need the -ing form after be, not the base form.
The he/she/it form of the present simple needs -s added to the base form.
"What do you do in your free time?"
"Mostly reading, and I've recently started painting."
"That's great — painting always seemed relaxing to me."
"It really is. I've been doing it every weekend."
