The French expression on dirait is widely used in spoken and written language. It comes from the verb dire (to say), conjugated in the conditional third person singular (on dirait = one would say / it would seem). The subject on is impersonal, and the phrase often introduces an impression, resemblance, assumption, or hypothetical situation.

In English, on dirait can translate as:

• it looks like
• it sounds like
• it seems like
• you’d think
• it’s as if
• one would say
• looks like (informal, colloquial)

The correct translation depends on the sentence structure and context.
