stickle
Stickle (noun) means a sharp point, such as a small spine or prickle.
Etymology
Comes from Middle English *stikel, *stykyl (found in compounds), which developed from Old English sticel ("a prickle, sting, goad"), itself from Proto-Germanic *stiklaz, *stikilaz ("sting, stinger, peak, cup, goblet"), related to the verb *stikaną ("to stick"). It is cognate with Dutch stekel, Icelandic stikill, and Gothic ?????? (stikls) (which in turn gave Russian стекло́ (stekló, "glass"), Polish szkło ("glass"), Lithuanian sti̇̀klas, and Romanian sticlă).
