The story

In Middle English, the second element was re-analyzed as or influenced by grom, grome (‘attendant’). Guma derives from Proto-Germanic *gumô (‘man, person’), from Proto-Indo-European *dʰǵʰm̥mō; it is cognate to Icelandic gumi.

  6. Englishtodaygroom

Apparently related to Middle Dutch grom (‘boy’), Old Icelandic grómr, gromr (‘man, manservant, boy’), Old French gromme (‘manservant’), and also to Middle Dutch grom (‘fish guts’), Middle Low German grôm (‘fish guts’), from the same Proto-Germanic root. Alternative etymology describes Middle English grom, grome as an alteration of gome (‘man’) with an intrusive r (also found in bridegroom, hoarse, cartridge, etc.), with the Middle Dutch and Old Icelandic cognates following similar variation of their respective forms.

Today it means

noun A man who is about to marry.
