"Where were you for the week?"

Translation: Ble buoch chi am yr wythnos?

[AndrewDu3]

As it's a question shouldn't it be fuoch rather than buoch?

[MrGWallCymraeg]

Persoanlly, I'd say "ble fuoch chi?" but I think there's a rule somewhere that "ble" doesn't create a mutation, possibly from "pa le"...
