I know I can say 'give him a shirt', which means there are two objects following the verb 'give'.
Can 'ensure' have the same function? Like, the government must ensure its people basic means of life.??
"ensure" is a verb meaning 'guarantee'. "it's people" is an indirect object like "him", and "basic means of life" is a direct object like "a shirt".
But the sentence won't be correct with "make sure".
