Where it comes from
The noun is borrowed from French fascine (“bundle of kindling; bundle of branches used to build defences, fill in ditches, etc.; logs arranged horizontally between piles on the banks of a watercourse as an erosion barrier”), from Old French faissine, from Latin fascīna (“bundle of sticks”), from fascis (“bundle of sticks, faggot, fascine; bundle, package; burden, load”) (ultimately from a late or pseudo-Proto-Indo-European root noun *bʰask- (“band; bundle”), actually originating from a substrate language or as an eastern Mediterranean Wanderwort) + -īna (the nominative, vocative, or ablative feminine singular of -īnus (suffix forming nouns)). The verb is derived from the noun.
