  • A prefix signifying in or into, used in many English words, chiefly those borrowed from the French. Some English words are written indifferently with en-or in-. For ease of pronunciation it is commonly changed to em-before p, b, and m, as in employ, embody, emmew. It is sometimes used to give a causal force, as in enable, enfeeble, to cause to be, or to make, able, or feeble; and sometimes merely gives an intensive force, as in enchasten. See in-.
  • A prefix from Gr. � in, meaning in. See In-.

Both Latin and Germanic, from Proto-Indo-European *en (“in, into”). Intensive use of Old French en-, an- due to confluence with Old Frankish *an- (intensive prefix), related to Old English on- (intensive prefix). More at in-, on-.
