1. \En-\
   1. [F. en-, L. in.] 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-}.
   2. A prefix from Gr. ? in, meaning in; as, encephalon,
      entomology. See {In-}.
   

2. \-en\
   1. A suffix from AS. -an, formerly used to form the plural of
      many nouns, as in ashen, eyen, oxen, all obs. except oxen.
      In some cases, such as children and brethren, it has been
      added to older plural forms.
   2. A suffix corresponding to AS. -en and -on, formerly used
      to form the plural of verbs, as in housen, escapen.
   3. A suffix signifying to make, to cause, used to form verbs
      from nouns and adjectives; as in strengthen, quicken,
      frighten. This must not be confused with -en corresponding
      in Old English to the AS. infinitive ending -an.
   4. [AS. -en; akin to Goth. -eins, L. -inus, Gr. ?.] An
      adjectival suffix, meaning made of; as in golden, leaden,
      wooden.
   5. [AS. -en; akin to Skr. -na.] The termination of the past
      participle of many strong verbs; as, in broken, gotten,
      trodden.
   

3. \En\, n. (Print.)
   Half an em, that is, half of the unit of space in measuring
   printed matter. See {Em}.
