Stuck on a couple this week.
18d)Carouses with one final replacing another in clubs (8)
I have ?LAS?ERS
26d)Latin title one favoured after breaking Priscian's head (5)
I have ?OPET
Looks like I might have gone wrong somewhere.
Thanks in advance for any assistance.
18d is a plural noun meaning 'carouses' (drinking sprees) with one word for 'final' being replaced by another word for 'final', the definition being 'clubs'.
