The word crimson has been recorded in English since 1400,[1:] and its earlier forms include cremesin, crymysyn and cramoysin (cf. cramoisy, a crimson cloth). These were adapted via Old Spanish from the Medieval Latin cremesinus (also kermesinus or carmesinus), the dye produced from Kermes scale insects, and can be traced back to the Turkish kırmızı (red in Turkish), which in turn stems from the Sanskrit krmi-ja, a compound meaning "produced by a worm" from krmih "worm" + -ja "produced" (from the Proto-Indo-European *gene-).
A shortened form of carmesinus also gave the Latin carminus, from which comes carmine.
Other cognates include the Old Church Slavic čruminu and the Russian čermnyj "red". Cf. also vermilion.
