FAQ
Frequently Asked Questions
It is non-standard. The correct forms are the phrasal verb 'watch out' (two words) or the interjection 'Watch out!'.
They are largely interchangeable as warnings. 'Look out' can sometimes be more immediate (duck!), while 'watch out' can imply sustained attention, but the difference is subtle.
It is too informal for formal writing. Use 'be aware of', 'exercise caution regarding', or 'note the risk of' instead.
Use 'watch out for' when specifying the danger or thing to be avoided (e.g., watch out for ice). No preposition is used when it's a general warning (e.g., Watch out!).
