Word Origin and History for aspirating



1725, "sound of the letter 'H'," especially at the beginning of a word, from Latin aspiratio "a breathing, exhalation, the pronunciation of the letter H" (see aspire).



"to pronounce with audible breath," 1700; perhaps a back-formation from aspiration (n.2), or from French aspirer (1520s), or directly from Latin aspiratus, past participle of aspirare (see aspire). Related: Aspirated; aspirating.
