Translation guide
The English word 'sooner' is primarily used in comparisons to indicate that something happens earlier than something else, or in the fixed expression 'sooner or later' meaning eventually. This guide covers how to express these ideas naturally in Japanese.

English 'sooner' is a comparative form, but Japanese does not have a direct one-word equivalent. Instead, use comparative structures like より早く or adverbs like もっと早く. Translating 'sooner' as 早く alone may not convey the comparative meaning.
