[name_f]Elsa[/name_f] has a sort of sweet-but-sharp vibe: cosy without being fluffy. It does bring to mind snow, winter, christmas markets, log cabins, ice, etc. – probably because of Frozen and because of its Scandinavian/German roots more generally.
As I say, I do think of Frozen, but not in a bad and serious way, kind of neutral – in the same way I’d think [name_f]Ariel[/name_f] → [name_m]Little[/name_m] Mermaid or [name_m]Casper[/name_m] → the Friendly [name_f]Ghost[/name_f]. [name_m]The[/name_m] association is just there, but it’s one element of the name for me?
