I’m sure this has been done before but I was just thinking about how Alchemy sounds really nice. Al for short, obviously.
For boys:
Alchemy
Currant
Errand
Filo
Shiver
Spending
Toboggan
For girls:
Anklet
Celery
Evil
Lightly
Maybe
Navy
Whimsy
Might work for both:
Ample
Denim
Frankly
What other random words sound like they’d make nice names if only they’d catch on? Obviously light-hearted and not actually suggesting anyone uses them (although…)
