Common mistakes

Become is followed directly by a noun or an adjective, never by as.

For translators

Meaning across languages Many languages use different verbs for a change in profession or role (become a doctor) and a change in state or quality (become cold); English uses become for both.
Grammar trap Irregular: become, became, become. The past participle is the same as the base form: it has become. Do not confuse this with the present participle becoming, used in continuous tenses: it is becoming.
