Unsolicited contact in hot tub by Mike (4)
I believe the answer is:
spam
'unsolicited contact' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'hot tub by mike' is the wordplay.
'hot tub' becomes 'spa' (I've seen this in another clue).
'by' means one lot of letters go next to another.
'mike' becomes 'M' (phonetic alphabet: alpha, bravo, charlie etc.).
'spa'+'m'='SPAM'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for spam that I've seen before include "Food" , "Unwanted communication" , "luncheon meat" , "unwanted delivery" , "Possible item from menu" .)
