How to Pronounce Irritability

Say it like this: ih-RIT-uh-BIL-ih-tee. The stress (loudest part) falls on the second syllable, 'RIT.' Think of it as four parts: ih-RIT-uh-BIL-ih-tee, with 'RIT' getting the most emphasis.

The word breaks into five syllables: ir-ri-ta-bil-i-ty. Each syllable gets its own beat when you say it slowly, and the second syllable (ri) is where the stress lands.

Many people stress the wrong syllable and say 'ir-it-uh-BIL-ih-tee' (stressing 'BIL'), but the correct stress is on the second syllable: 'IR-it-uh-bil-ih-tee.' Remember: the stress comes early in the word, not late.

Irritability means being very quick to get annoyed, frustrated, or angry—sometimes even over small things. It's like having a shorter fuse than usual, where normal situations bother you more than they normally would.

It comes from the Latin word 'irritare,' which means 'to provoke' or 'to stir up.' The ending '-ability' turns it into a noun meaning 'the quality or state of being easily irritated.'

'Irritate,' 'irritant,' and 'irritable' all come from the same Latin root 'irritare.' If someone is 'irritable,' they have a tendency toward 'irritability,' and an 'irritant' is something that causes that irritated feeling.

You might say, 'The patient reported increased irritability over the past two weeks,' or 'The doctor asked whether the client had noticed any changes in irritability.' The word describes a pattern or tendency, not just a single moment of being annoyed.

Not really—there's no common medical abbreviation for this word. You'll usually see it written out in full as 'irritability,' though people might also use the related adjective 'irritable' in casual speech.
