supply

Noun

derivative of supply entry 2

Verb

Middle English supplien "to fill up, accomplish, discharge (an office)," borrowed from Middle French soupplier "to add what is lacking to" (also souppleer, suploier "to make up for [a lack, deficiency]," suppleer a, soupplir "to replace"), going back to Latin supplēre "to fill up, complete, raise (a military unit, crew) to its full complement, make good a deficiency in," from sub- sub- + plēre "to fill" — more at full entry 1

Note: Though the French verb receives its semantic start with Latin supplēre, none of the great variety of formal outcomes appear to be directly traceable to it. Variants such as suploier and soupplier have evidently been crossed with outcomes of supplicāre "to sue for forgiveness, supplicate" (see also suppliant entry 1). The form suppleer, which may be directly behind Modern French suppléer, appears to have been both latinized (after supplēre) and conformed to verbs such as créer. The variant soupplir suggests the general Romance re-formation *supplīre (compare Old Occitan and Spanish suplir, Italian sopperire).
