filter

filter: [14] Ultimately, filter is the same word as felt – and indeed that is what it first meant in English (‘They dwell all in tents made of black filter’, John Mandeville, Travels 1400). It comes via Old French filtre from medieval Latin filtrum, which was borrowed from prehistoric West Germanic *filtiz, source of English felt. The modern sense of filter did not develop until the 17th century; it came from the use of felt for removing impurities from liquid. The derivative infiltrate dates from the 18th century. (The homophonic philtre [16] is not related; it comes ultimately from Greek phílos ‘beloved’.)
