formido

Latin

Etymology

The verb is probably derived from the noun.[1] Their origin is unknown:

  • Possibly from the root Proto-Indo-European *dʰer- (to hold) (the same of firmus), as the fear that makes one rigid.
  • Alternatively cognate with Ancient Greek μόρμορος (mórmoros, fear, panic), μύρμος (múrmos, fear) and μορμώ (mormṓ, bogey, she-monster), with the same dissimilation *morm- > form- seen in formīca and possibly fōrma.[2][1]
    If this is of Proto-Indo-European origin, it would appear to be a reduplication of a root *mer-, possibly the same root as *mer- (to disturb) and/or the source of *mor- (incubus, mare (evil female spirit of nightmares)) (which is otherwise thought to be from *mer- (to disappear, die)). (Can this(+) etymology be sourced?) However, de Vaan reconstructs only a stem *mormo- which he does not allow an etymology.
    If not Indo-European, then a substrate origin must be considered, which the variation of forms in Greek and morphological obscurity in both languages make likely. (Can this(+) etymology be sourced?)

The suffix component -īd- is unexplained in either case, but compare -idus (with different vowel length), (forming nouns).
