Ferment foment fever - apply heat(causes liquid to bubble, boils via fever)

late Middle English: from Old French ferment (noun), fermenter (verb), based on Latin fermentum ‘yeast’, from fervere ‘to boil

fever (n.)
earlier also feaver, late Old English fefor, fefer "fever, temperature of the body higher than normal," from Latin febris "fever," related to fovere "to warm, heat," which is probably from PIE root *dhegh- "burn" [??] (source also of Gothic dags, Old English dæg "day," originally "the heat;" Greek tephra "ashes;" Lithuanian dāgas "heat," Old Prussian dagis "summer;" Middle Irish daig "fire"); but some suggest a reduplication of a root represented by Sanskrit *bhur- "to be restless"

foment (v.)
early 15c., "apply hot liquids," from Old French fomenter "apply hot compress (to a wound)" (13c.), from Late Latin fomentare, from Latin fomentum "warm application, poultice," contraction of *fovimentum, from fovere "to warm".

foam
From Middle English fom, foom, from Old English fām, from Proto-Germanic *faimaz, from Proto-Indo-European *(s)poHy-m-os, from *(s)poH(y)- (“foam”). Cognate with German Feim (“foam”), Latin spūma (“foam”), Latin pūmex (“pumice”), Sanskrit फेन (phéna, “foam”), possibly Northern Kurdish fê (“epilepsy: foam at the mouth?)

Foam fume spume sponge fungi? froth fart? (Fufu in Samoan)
