Hi Nunoesque
6 a female spouse without last letter, stopped by “a”
7 d words for outburst anger and dad all backwards give you a pre prandial snifter
19d think Cockney rhyming slang for courage
23a replace first letter of word for liniments with a n for new to give you word for fancies (ideas).
I think 26 a has been covered already.
Re 16 d I am less sure but the last three letters are a word for dessert backward and the rest I think is a pronoun for man and a three letter description of a clumsy fellow.
Hope that helps.
