Beat somewhat shorter finalist in Omnium? (5)
I believe the answer is:
minim
'beat somewhat' is the definition.
'minim' can be an answer for 'beat' (I've seen this before). I am not certain of the 'somewhat' bit.
'shorter finalist in omnium?' is the wordplay.
'shorter' becomes 'mini' (I can't justify this - if you can you should believe this answer much more).
'finalist in' indicates one should take the final letters.
The final letter of 'omnium' is 'm'.
'mini'+'m'='MINIM'
Can you help me to learn more?
(Other definitions for minim that I've seen before include "Note equal to two crochets" , "Feature of a score" , "Quarter of a breve" , "Beat" , "Note of two crotchets" .)
