Meaning and Usage
The verb 明かす (あかす) primarily means "to reveal" or "to disclose" something hidden, such as a secret or truth. It is often used in formal or serious contexts where important information is being uncovered.
Different Contexts

Common Collocations
- 秘密を明かす: to reveal a secret
- 真実を明かす: to reveal the truth

Nuances and Tips
When using 明かす to mean "reveal," it often implies a deliberate or significant disclosure, not casual sharing. Avoid confusing it with simpler verbs like 教える (to teach/tell) or 見せる (to show), which are less formal and less about secrets.
The phrase 夜を明かす is a fixed expression and does not relate to revealing information but to spending the night awake or somewhere overnight.
