รัก

Built from

From a Mon-Khmer language; ultimately from Proto-Mon-Khmer *r(a)k (“to love; beloved, dear”). Cognate with Lao ຮັກ (hak), Isan ฮัก, Northern Thai ᩁᩢ᩠ᨠ, Khün ᩁᩢ᩠ᨠ, Lü ᦣᧅ (hak), Khamti ꩭၢက︀်ႉ, Shan ႁၵ်ႉ (hâ̰k), Tai Nüa ᥞᥐ (hak). Outside Tai-Kadai, cognate with Khmer រាក់ (rĕək, “friendly, cordial, pleasant; intimate, affectionate”), as in រាក់ទាក់ (reak-teak, “friendly, warm, pleasant”). The Proto-Mon-Khmer root possibly represents an allofam of the proto-root *mr[a]k, *rmr[a]k (compare Proto-Mon-Khmer *mak ~ *ma(a)k (“to like, love”)), whence Khmer ម្រក់ (mrŭək, “girl's friend of same sex, man's friend's wife”), and possibly Thai มลัก (má-lák, “to love, to like”). Uncertain. Cognate with Lao ຮັກ (hak). Compare Sanskrit आर्क (ārka, “crown flower”), Pali akka. From Proto-Tai *rakᴰ (“lacquer”). Cognate with Lao ຮັກ (hak), Northern Thai ᩁᩢ᩠ᨠ, Khün ᩁᩢ᩠ᨠ, Lü ᦣᧅ (hak), and Shan ႁၵ်ႉ (hâ̰k). Compare Sanskrit लाक्षा (lākṣā, “a species of plant”).
