A. adj. I. 1. a. Said of a material substance in that condition (familiar as the normal condition of water, oil, alcohol, etc.) in which its particles move freely over each other (so that its masses have no determinate shape), but do not tend to separate as do those of a gas; not solid nor gaseous. Hence, composed of a substance in this condition.

2. Phonetics. A name applied to the sounds denoted by the letters l, m, n, r, or (by some writers) only to those denoted by l and r.
The name (L. liquidæ, sc. litteræ) is a literal translation of the Gr. ὑγρά (sc. στοιχεῖα) applied to λ, µ, ν, ρ, on account of their flowing and easy sound as compared with other consonants, or perh. as having an indeterminate or unstable character between consonant and vowel (cf. the application of ὑγρός to a vowel of variable quantity; also the term ἡµίϕωνα ‘semi-vowels’, applied to the ‘liquids’ and σ). A somewhat analogous term is the F. mouillé lit. ‘wet’, used to denote the palatalized pronunciation of l and some other consonants.
