liquid

Etymology

From Middle English liquide, from Old French liquide, from Latin liquidus (“fluid, liquid, moist”), from liqueō (“to be liquid, be fluid”), ultimately from Proto-Indo-European *wleykʷ- (“to flow, run”). Doublet of liquidus. As a term for a consonant, it comes from Latin liquida (cōnsōnāns), a calque of Ancient Greek ὑγρὸν (σύμφωνον) (hugròn (súmphōnon), “liquid consonant”).

     The dawn of the oil age was fairly recent. Although the stuff was used to waterproof boats in the Middle East 6,000 years ago, extracting it in earnest began only in 1859 after an oil strike in Pennsylvania. […] It was used to make kerosene, the main fuel for artificial lighting after overfishing led to a shortage of whale blubber. Other liquids produced in the refining process, too unstable or smoky for lamplight, were burned or dumped.

3. (phonetics) Any of a class of consonant sounds that includes l and r.

   Hypernyms: approximant, consonant

   Coordinate term: glide

     Many female forenames are regarded as euphonyms. What is and is not euphonious is necessarily subjective, but it could be suggested that names containing labials (b, m), sibilants (s, sh) and liquids (l, r) are more likely to be euphonyms than those that do not.

   • 1999, Ingo Plag, Morphological Productivity, page 86:

     […] -able does not attach to verbs ending in a postconsonantal liquid […]
