Breakdown of Ещё бы!
Questions & Answers about Ещё бы!
It is a fixed conversational expression, basically an exclamation of strong agreement or obviousness.
Depending on context and tone, it can mean things like:
- Of course!
- Definitely!
- You bet!
- No wonder!
It is not usually understood word-by-word in normal speech. Learners should treat it as an idiomatic phrase.
Literally, the words are not very transparent in English.
- ещё often means still, yet, more, else
- бы is a particle often connected with hypothetical or conditional meaning
But in Ещё бы!, the phrase functions as a set expression, so the literal meaning is much less important than the idiomatic one. A rough historical sense is something like Why, of course it would be so!, but that is not how you should translate it in most real situations.
