ဆုံ

• IPA^(key): /sʰòʊɴ/
• Romanization: MLCTS: hcum • ALA-LC: chuṃ • BGN/PCGN: hson • Okell: hsouñ

From Proto-Lolo-Burmese *dzum³/¹ ~ tsum¹ (“pair, even number”), from Proto-Sino-Tibetan *dzum ~ tsum (“pair”) (STEDT). By synchronic analysis, a causative formation related to စုံ (cum, “to be completed, sufficient”); see there for more.

1. to meet, come together, converge
2. to coincide
3. to pool or share a purchase
4. to be identical

ဆုံ • (hcum)

1. junction, intersection, confluence

From Proto-Tibeto-Burman *(t)sum (“mortar”); cognate with Mizo [Term?] (sûm, “mortar”) (STEDT). Despite MED grouping the terms together, unclear if related to the "coincide" sense of Etymology 1. If related, perhaps the mortar was seen by Tibeto-Burman tribes as the tool where ingredients met and mashed together.

1. mortar, mill, press, bowl (of a tobacco pipe)
