You really can't be sure if the goddess names actually mean anything. Some things have meanings and some don't. Like I don't think Hyrule means anything, unless it's pun or something I'm not aware of, but Termina is a wordplay on 'Terminate' like how it'll be destroyed.
Anyway about some possiblilities about remember Zelda feels regret for causing the problems in OoT but then helps to stop it and Ganondorf causes problems and therefore 'pandemonium'?
