Other forms: warnings
A warning is a message that danger or trouble is coming. A weather warning, without warning, a final warning.
It can be official — a flood warning, a health warning — or personal: a warning to stop. Give warning, issue a warning and heed a warning are the standard verbs. Without warning means suddenly and with no sign beforehand. In employment, a verbal warning and a written warning are formal stages of discipline. Note warning sign, both the literal object and the figurative early indication that something is going wrong.
