กำลัง

Borrowed from Middle Khmer kuṃlāṃṅa (“strength; vigour; brawn; force; power; might; energy; clients; dependents; servants; helper; aid; ally”), Angkorian Old Khmer kanlāṅ, kanlaṅ (“strength; force; power; one who is strong or powerful”), or Pre-Angkorian Old Khmer kanlaṅ, kanlāṅ (“strength; force; power; one who is strong or powerful”); compare Modern Khmer កម្លាំង (kɑmlang). Cognate with Lao ກຳລັງ (kam lang). The Khmer word is derived from -m- infixation of the root ខ្លាំង (khlang, “strong; vigorous; robust”), whence also Thai ขลัง (klǎng, “magically potent; magical; having supernatural powers; miraculous”). Semantic extension of the "force, power" sense of Etymology 1. The auxiliary verb evolved from the noun senses and was first attested in mid-19ᵗʰ century writing. It supplanted the earlier postverbal auxiliary อยู่ (yùu, “to stay”) for marking the progressive or continuous aspect. The current use of preverbal กำลัง (gam-lang) is either in addition to, or instead of, postverbal อยู่ (yùu).
