Premise

noun/PREM-iss/

Meaning

An idea you accept as true and use as the base for an argument or story.

In context
The film's premise is that a boy can talk to animals in the bush.

Remember it

Premise = pre + 'mise' (put) — an idea put down first, before the rest is built on it.

Use it well

Use for the starting idea of an argument; don't confuse it with 'promise'.
