Need the past tense of trnout. Is it trnul or trl? I know that for past tense you drop the -nout for -nout verbs. Ex: Poslechnout is poslechl and if there is a vowel in front of the -nout, the ending is -ul, like zahynul. Any clarification?
Poslechnout - poslechl is correct, but poslechnul can be used as well. As for "trnout", I never heard anything else than "trnul".
