verb

Treat (a metal object) with a flux to promote melting.
Example sentences

Origin

late Middle English: from Latin fluxus, from fluere 'to flow'.

More
• affluent from (Late Middle English):

From Latin affluere ‘flow towards’, affluent was originally used to describe water either flowing towards a place or flowing freely without any restriction.

Related words, all based on Latin fluere ‘to flow’ are fluent (late 16th century) and fluid (Late Middle English); flume (Middle English) originally a stream; flux (Late Middle English) a state of flowing; effluent (Late Middle English) something that flows out; and superfluous (Late Middle English) ‘overflowing’.
