Attempt to claim one record that's in three parts (7)
I believe the answer is:
trilogy
'in three parts' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'attempt to claim one record' is the wordplay.
'attempt to' becomes 'try' (I've seen this in other clues).
'claim' means one lot of letters goes inside another (inserted letters are claimed or taken in).
'one' becomes 'i' (Roman numeral).
'record' becomes 'log' (log is a kind of record).
'i'+'log'='ilog'
'try' going around 'ilog' is 'TRILOGY'.
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for trilogy that I've seen before include "Group of three linked works" , "Set of three literary or dramatic works" , "Group of three related works" , "collected works" , "Three-volume work" .)
