Short form related to Germanic names; possibly from Old English 'glidan' meaning 'to glide.'
Glida is likely related to Germanic names and may connect to the old English root glidan, meaning to glide. That gives the name an understated sense of motion and smoothness, as if its meaning lives in the sound itself.
Glida is short, uncommon, and quietly graceful. It does not announce itself loudly, but it leaves an impression because it feels light and slightly unusual. The name has a modest, almost vintage simplicity that makes it easy to picture in different eras. Its appeal lies in that restrained elegance: familiar in structure, but not overused.
