English ramson (Old English hramsan) is of unclear origin; cognates are found in several Germanic (e.g., Swedish ramslök and regional German Ramsen) and Slavonic languages (e.g., Serbian cremoš [цремош] and Russian cheremsha [черемша]). There are, however, a few possibly related words in other Indo-European tongues: Greek krommyon [κρόμμυον] and Sanskrit krimighna [कृमिघ्न] "onion", and maybe Welsh craf "garlic".
