insulate

From Latin īnsula (“isle, island”) +‎ -ate (verb-forming suffix) or from Late Latin īnsulātus (“made an island”), see etymology at -ate. First attested in the 16th century; the general verb īnsulō (“insulate”) is attested only in New Latin and postdates the English term, but influence from an otherwise unattested Medieval Latin counterpart cannot be ruled out.^[1] Piecewise doublet of isolate.
