How it's used
This idiom describes a situation where two or more people share a secret or a mutual understanding without needing to verbalize it. It often carries a slightly conspiratorial or knowing tone, implying that the silence is intentional and shared. It is frequently used in social contexts where social cues or past experiences make explicit communication redundant.
Examples
We have a tacit understanding, no need to say it out loud.
The two of them have a tacit understanding; everyone knows what happened.

Common mistake
Learners often mistake this for a simple synonym of knowing something, but it specifically requires a shared, unspoken agreement between parties. It is not used to describe one person simply knowing a fact on their own.
