สนิท

From Pali siniddha (“gluey, sticky; smooth, sleek; lovely, pretty; etc”), ultimately from Sanskrit स्निग्ध (snigdha, “idem”), according to the Royal Institute Dictionary 2011; but more likely to be from Old Khmer ត្និត៑ (tnit, “close; intimate”) or from Sanskrit सनीड (sanīḍa, “close; closely united or related; etc”).

Compare Modern Khmer ស្និទ្ធ (snət, “close, intimate; beloved, dear”).
