köken: From Middle High German nagel, from Old High German nagal, from Proto-West Germanic *nagl.
aile: an den Nagel hängen, auf den Nägeln brennen, Daumennagel, den Nagel auf den Kopf treffen, Eisennagel, festnageln, Fingernagel, Fußnagel, Nagelbett, Nagelbrett
köken: Inherited from Old Spanish clavo, from Latin clāvus. The conservation of Latin /kl-/ is irregular (normally the result is /ʎ/, but cf. claro), which might imply a degree of Latin influence. Still, it is difficult to regard such a mundane term as learned or even semi-learned. First attested in the twelfth century. Compare Portuguese cravo.
aile: agarrarse a un clavo ardiendo, árbol del clavo, arrimar el clavo, clavete, clavetear, clavo de chilla, clavo de olor, clavo de rosca, como un clavo, dar en el clavo
köken: From Proto-Italic *klāwos, from Proto-Indo-European *kleh₂w-o-s, from *kleh₂u- (“nail, pin, hook - instruments, of old use for locking doors”). Cognate with Ancient Greek κλείς (kleís, “key”) and Old Church Slavonic ключь (ključĭ, “key”). Latin clāvis (“key”) is either a secondary i-stem derivation, or a loanword from Ancient Greek κληΐς (klēḯs).
spike (very large nail; anything resembling such a nail; sharp peak in a graph) · spica, spike (kind of inflorescence in which sessile flowers are arranged on an unbranched elongated axis)
çekim: çoğul spící · tamlayan spící
köken: From Middle English spike, from Old Norse spík (“spike, sprig”), from Proto-Germanic *spīkō (“stick, splinter, point”), from Proto-Indo-European *spey- (“to be pointed; sharp point, stick”). Cognate with Scottish Gaelic spìc.
