How to use "a short fuse"

What Does "a short fuse" Mean?

• The idiom "a short fuse" describes someone who is easily angered or has a low tolerance for frustration. It implies a quick temper and a tendency to react impulsively and angrily to minor provocations. It doesn't refer to a literal fuse.
• The origin of the phrase likely comes from the literal fuses used in explosives. A short fuse would result in a quicker, more immediate explosion.
• Register: Neutral

How to Use It

• The phrase "a short fuse" is typically used as a descriptor for a person's temperament. It can be modified with adverbs (e.g., "He has a very short fuse") or used in possessive constructions (e.g., "His short fuse is well-known"). It can also be used in negative constructions (e.g., "He doesn't have a short fuse").
• Using "a short fuse" to describe something other than a person's temper (e.g., "This project has a short fuse") would be unnatural and confusing. Overly literal interpretations should also be avoided.
