interlard

The verb is derived from Late Middle English interlarden (“to mix fat into (something)”), borrowed from Old French entrelarder (modern French entrelarder (“(cooking) to put pieces of bacon into meat, interlard; (figurative) to furnish by interspersing, adorn something all over (e.g., a text, with verses, metaphors, etc.)”)), from entre- (prefix meaning ‘in between, between’) (from Latin inter-, ultimately from Proto-Indo-European *h₁entér (“between”)) + larder (“to smear with lard or fat, to lard”) (from lard (“bacon fat, lard”) + -er (a variant of -ier (suffix forming verbs))). Lard is from Latin lārdum, lāridum (“bacon fat, lard”); further etymology uncertain, probably borrowed from or related to Ancient Greek λᾱρῑνός (lārīnós, “fat, fatted”, adjective), possibly from λᾱρός (lārós, “delicious; sweet”) (possibly from Proto-Indo-European *leh₂w- (“to gain; to seize; benefit, prize”)) + -ινός (-inós) (a variant of -ῐνος (-ĭnos, suffix forming adjectives)). By surface analysis, inter- (prefix meaning ‘between’) + lard (verb).
