Slightly pissed Yankee follows hints (5)
I believe the answer is:
tipsy
'slightly pissed' is the definition.
'tipsy' can be an answer for 'pissed' (synonyms). I'm not certain of the 'slightly' bit.
'yankee follows hints' is the wordplay.
'yankee' becomes 'Y' (phonetic alphabet: alpha, bravo, charlie etc.).
'follows' is a charade indicator (letters next to each other).
'hints' becomes 'tips' ('tip' can be a synonym of 'hint').
'y' after 'tips' is 'TIPSY'.
Can you help me to learn more?
(Other definitions for tipsy that I've seen before include "Rather drunk" , "Merry, squiffy" , "A bit drunk" , "1 over 8" , "Woozy" .)
