More mistakes(2)
Handle with care. Do not use as a verb form like 'heads-up me' — use it as a noun ('give someone a heads-up') or adjective ('heads-up email'). Avoid overusing in highly formal written communication.
- ✕This is a heads-up important message.✓This is a heads-up: the system will be down tomorrow.
Heads-up is not an adjective meaning 'important.' Use it as a noun to signal advance notice.
