Etymology

Origin of irascible

First recorded in 1350–1400; Middle English irascibel from Late Latin īrāscibilis, equivalent to Latin īrāsc- (stem of īrāscī “to grow angry”; equivalent to īr(a) ire + -ā- theme vowel + -sc- inchoative suffix + infinitive ending; see -esce) + -ibilis -ible

Explanation

If you're irascible, you get angry easily — perhaps blowing up in rage when someone brushes into you. Irascible comes from the Latin root ira, which means "anger" or "rage," the same root that gives us the word ire, "anger." The -sc in the middle of irascible, means "becoming," so irascible doesn't just mean you're angry — it's got action built into it. If you're looking for a fight most of the time, then you're irascible — ready for the spark that's going to set you on fire.
