How do you pronounce his name?
There’s no shame in looking at an unusual surname and not having the slightest idea how to pronounce it. And ‘Gloukh’ is nothing but an unusual surname.
It’s hard for native English speakers to get the Hebrew pronunciation of his name spot on - but it’s pretty close to ‘glook’. Like ‘glue’ with a K on the end.
Die germanisierte Form des Names ist Glokh, Gloch oder Gluh. Ich werd irgendwie nicht schlau daraus.
