This should come in handy.
I'll repeat a mnemonic I wrote elsewhere: an OTTer needs A HOLt (for those who may not know, otters' nests are properly called holts).
You can also have ahova or ahonnan :-)
Can I also say: Ott tüszentek, ahol te?
What is the purpose of "Ott" in this sentence? Are "Ott" and "ahol" prepositions that go together in sentences like this?
Ott/ahol are a pair. You cannot use ahol in this type of sentence without an ott in the other clause.
How about, Tuszentek ahol te tusszentesz?
No. You need the "ott" to anchor the "ahol"
Is 'ssz' in 'tüsszent' pronounced as 's-sh', and in 'rosszul' as 's-s'?
the ssz in "tüsszent" and "rosszul" should sound the same.
the long version of sz is ssz
tüsszent: IPA tysːɛnt
rosszul: IPA rosːul
