annoyance (n.)

late 14c., "vexation, trouble," from Old French enoiance "ill-humor, irritation," from anuiant, present participle of anuier "to be troublesome, annoy, harass" (see annoy). Meaning "state of being annoyed" is from c. 1500, as is the sense of "that which annoys." Earlier, annoying was used in the sense of "act of offending" (c. 1300) and a noun annoy (c. 1200) in the sense "feeling of irritation, displeasure, distaste."
