Translation guide
The English prefix 'pre-' is used to form words meaning 'before' in time, order, or position. In Japanese, this concept is expressed through prefixes, adverbs, or compound structures rather than a single direct equivalent.
Attach 前 (まえ) after a noun or verb phrase to mean 'before'. This is the most common way to express 'pre-' in temporal contexts.

Unlike English, Japanese does not have a single prefix that can be attached to any word to mean 'pre-'. Instead, use specific compounds or phrases like 前 (まえ/ぜん) or 事前 (じぜん).
To say 'before doing something', use the dictionary form of the verb + 前に (まえに). For example, 食べる前に (before eating).
