Translation guide
The English word "forever" can express an endless duration, a very long time, or a persistent state. Japanese uses different expressions depending on whether you mean eternity, a long but finite time, or a continuous action. This guide helps you choose the most natural option.
Expressing that something will last for all future time, without end.
The most direct equivalent for 'forever' in the sense of eternity. Used in both spoken and written Japanese, but can sound slightly formal or poetic.

Literally 'until whenever', this is a very common and natural way to say 'forever' in everyday speech. It implies an indefinite, long-lasting duration.

English uses 'forever' hyperbolically much more often than Japanese. In many cases, ずっと or いつも is more natural than 永遠に. Using 永遠に for a short wait can sound overly dramatic or unnatural.
ずっと emphasizes continuous duration ('all the time'), while いつも emphasizes habitual frequency ('always'). For example, ずっと待っている means 'I've been waiting forever (continuously)', while いつも待っている means 'I'm always waiting (on every occasion)'.

Formal, poetic. In casual speech, ずっと好きだよ is more common.
