"cuando" doesn't seem like latin, but like spanish, there is no verb "cuandere" in latin, as far as I know...
Edit: my latin is kinda rusty though, and it sucked to begin with, so don't trust me.
This would be a good starting place for latin translations:

Second edit: My latin sucks indeed. Cuando means "I see". Still not gonna translate that entire thing though.
