   • 2012 мај 5, Phil McNulty, “Chelsea 2-1 Liverpool”, in BBC Sport‎^[1] ((Молимо наведите језик навода)):Категорја:Наводи са недостајућим параметром за језик

     He met Luis Suarez's cross at the far post, only for Chelsea keeper Petr Cech to show brilliant reflexes to deflect his header on to the bar. Carroll turned away to lead Liverpool's insistent protests that the ball had crossed the line but referee Phil Dowd and assistant referee Andrew Garratt waved play on, with even a succession of replays proving inconclusive.

2. (linguistics) The descendant of an earlier language element, such as a word or phoneme, in a daughter language.
3. The descendant of anything from an earlier time, such as a cultural myth.
   • Brinton

     The superstition of the loup-garou, or werewolf, belongs to the folklore of most modern nations, and has its reflex in the story of "Little Red Riding-hood" and others.
