means A resinous substance secreted by the lac insect, used to make shellac and dyes — and, separately, the Indian numeral for one hundred thousand (100,000).

from From Hindi/Urdu 'lakh,' tracing back to Sanskrit 'lakṣa,' meaning both the resin and the number 100,000 — the two senses have been bundled together since antiquity, since the resin was traded and counted in such large quantities. The word entered English through trade contact with South Asia, arriving via Hindi and Persian intermediaries, and splitting into two familiar English uses: the sticky 'lac' of shellac, and 'lakh' as the number.
