Irascible Has an Angry History
If you try to take apart irascible on the model of irrational, irresistible, and irresponsible you might find yourself wondering what ascible means—but that's not how irascible came to be. The key to the meaning of irascible isn't the negating prefix ir- (which is the form of the prefix in- that is used before words beginning with "r"), but rather the Latin noun ira, meaning "anger." From ira, which is also the root of irate and ire, came the Latin verb irasci ("to become angry") and the related adjective irascibilis, the latter of which led to the French word irascible. English speakers borrowed the word from French in the 16th century.
