See bright star Mike ultimately dominate part of tennis match (4,4)
I believe the answer is:
love game
'tennis match' is the definition.
The definition suggests a singular noun which matches the answer.
'see bright star mike ultimately dominate' is the wordplay.
'see' becomes 'lo' (archaic exclamation meaning 'look!').
'bright star' becomes 'vega' (I've seen this in another clue).
'mike' becomes 'M' (phonetic alphabet: alpha, bravo, charlie etc.).
'ultimately' says to take the final letters.
The last letter of 'dominate' is 'e'.
'lo'+'vega'+'m'+'e'='LOVE GAME'
'part of' is the link.
Can you help me to learn more?
(Another definition for love game that I've seen is " (Tennis) play in which the loser gets no score".)
