different between mercurial vs irresponsible

English

Etymology

Noun sense 1 (“(obsolete) plant known as mercury”) is from Middle English mercurial, mercuryal (“a plant, probably the goosefoot (Chenopodium); (possibly) dog's mercury (Mercurialis perennis)”), from Anglo-Norman mercurial and Old French mercurial, or directly from their etymon Latin mercuri?lis (“a plant, probably annual mercury (Mercurialis annua)”), from mercuri?lis (“pertaining to the Roman god Mercury”, adjective), from Mercurius (“the Roman god Mercury”) + -?lis (suffix forming adjectives of relationship from nouns).

Later adjective and noun uses may have been directly derived from Latin mercuri?lis (adjective), whence Middle English mercurial, Mercurial (“under the astrological influence of the planet Mercury”).
