The singular is "Umlaut" (masculine, so "der Umlaut"). Plural: die Umlaute (except in the Dative Case, in which case it's: den Umlauten).
Visited Nürnberg last month. In my judgement: A very picturesque town.
The accepted English name is: Nuremberg.
If you liked their Racial Purity Laws, you'll love their sausage (Fränkische Bratwürste a.k.a. Nürnberger). /s
Regards,
TY. I was only 10-13 back then. We were in Nurnberg for about a year in 1957-58 as my father was with a tank/armor battalion. I recall him taking us to Dachau as he had been with the liberating force in WWII. I recall Stuttgart more as we were there in 1958-60.I also used to catch space A hops to visit my father and mother when he was assigned to EUCOM in 67-70 between his two Vietnam tours. I recall the bombed out area of Nurnberg. They had already worked hard repairing the damage. I recall the Germans digging in trash cans in 57-59. Sad.
