rather; instead; better
むしろ expresses that one option is more appropriate or preferable than another, often correcting an assumption.
むしろ means 'rather' or 'instead', and is used when you want to say that, compared to what was said or assumed, the opposite or a different thing is more true or better. It often appears in sentences like 'A rather than B' or 'It's more like B than A'.
You can use it to politely correct someone's idea, or to state your own preference when comparing options. It's common in both speaking and writing, though in casual speech you might hear it less often than in formal settings.
Note that むしろ often appears with structures like ~というより、むしろ~ (rather than ~, more like ~) or ~より、むしろ~ (more ~ than ~). It does not change the conjugation of the verb or adjective that follows.
