A couple of syllables to cheer when throwing up a drop of red (7)
I believe the answer is:
trochee
'a couple' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'syllables to cheer when throwing up a drop of red' is the wordplay.
'to cheer' can be anagrammed to 'TROCHEE'.
Though, I'm not sure how the anagram is indicated.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for trochee that I've seen before include "service, for example" , "Using foot" , "To cheer about this metrical unit" , "Long-short metric foot" , "poetic feature" .)
