felt: [OE] Etymologically, felt is a fabric that is formed by ‘beating’ (as indeed is the case, for it is made from compressed fibres). The word comes via West Germanic *feltaz or *filtiz (source also of German filz and Dutch vilt ‘felt’, and of English filter) from prehistoric Indo- European *peldos, a derivative of the same base as produced Latin pellere ‘strike, beat’ and the second syllable of English anvil. => anvil, filter
