When should I use "a" and when "ab"?
They are essentially the same thing, but use "a" before a consonant and "ab" before a vowel."
I was wondering if it might be that. Thank you!
Souldn't it be "urbem"?
No. Ab + Ablative. Always.
Easy to remember: Ablative with Ab.
And "Ad with Adcusative" ,;)
Why not urbem?
"Ab" takes an ablative object, not an accusative one.
Is this 'ab' related to German 'ab' they seem to convey similar notions.
Tracing back the etymologies for Latin "ab" and German "ab" shows that they are indeed distantly related.
Sounds like he's saying "veneunt"
