For a wedding with many guests, the groom may also ask other male friends and relatives to act as ushers without otherwise participating in the wedding ceremony; their sole task is ushering guests to their seats before the ceremony. Ushers may also be hired for very large weddings.
In a military officer's wedding, the roles of groomsmen are replaced by swordsmen of the sword honor guard. They are usually picked as close personal friends of the groom who have served with him. Their role includes forming the traditional saber arch for the married couple and guests to walk through.
The first recorded use of the word ‘groomsmen’, according to the Oxford English Dictionary, was as recently as 1698, although the words ‘bride’ and ‘groom’ both date back to Old English.[1]
