An assumption is something taken to be true without proof.
The idea
Assumption is countable. Use an assumption that before a clause and assumptions about before a topic.
Examples
- Our plan rests on the assumption that the bridge will reopen soon.
- The survey challenged her assumptions about city life.
- It was an assumption, not a fact supported by evidence.
- Before hiring anyone, the owner questioned an assumption about experience.
- Their assumption proved wrong when the shop stayed open late.
- Do not make assumptions about what your neighbours need; ask them.

Watch out
An assumption is not necessarily supported by evidence, and it may turn out to be false.
