Suggestions Yankee is a little intoxicated (5)
I believe the answer is:
tipsy
'little intoxicated' is the definition.
'tipsy' can be an answer for 'intoxicated' (similar in meaning). I'm unsure of the 'little' bit.
'suggestions yankee' is the wordplay.
'suggestions' becomes 'tips' (tip is a kind of suggestion).
'yankee' becomes 'Y' (phonetic alphabet: alpha, bravo, charlie etc.).
'tips'+'y'='TIPSY'
'is a' acts as a link.
Can you help me to learn more?
(Other definitions for tipsy that I've seen before include "Woozy" , "A bit drunk" , "Loaded" , "1 over 8" , "Slightly drunk" .)
