LIQ'UID, a. [L. liquidus, from liquo, to melt, Ir. leagham; probably from flowing, and coinciding with Sax. loge, water, L. lix, and lug, in Lugdunum, Leyden, Lyons.]

1. Fluid; flowing or capable of flowing; not fixed or solid. But liquid is not precisely synonymous with fluid. Air is fluid, but not liquid.
2. Soft; clear; flowing; smooth; a, liquid melody. – Crashaw.
3. Pronounced without any jar; smooth; as, a liquid letter.
4. Dissolved; not obtainable by law; as, a liquid debt. [Obs.] Ayliffe.
