|Word origin||The word flirt was originated in Mid 16th century: apparently symbolic, the elements fl- and -irt both suggesting sudden movement; compare with flick and spurt. The original verb senses were ‘give someone a sharp blow’ and ‘sneer at’; the earliest noun senses were ‘joke, jibe’ and ‘flighty girl’ (defined by Dr Johnson as ‘a pert young hussey’), with a notion originally of cheeky behaviour, later of playfully amorous behaviour.||The word tease was originated from Old English tǣsan, of West Germanic origin; related to Dutch teezen and German dialect zeisen, also to teasel. Sense 1 is a development of the earlier and more serious ‘irritate by annoying actions’ (early 17th century), a figurative use of the word’s original sense.|
