Clamour to include lively tune in collection of one hundred (7)
I believe the answer is:
century
'collection of one hundred' is the definition.
'century' can be an answer for 'hundred' (synonyms). I'm not certain of the 'collection of one' bit.
'clamour to include lively tune' is the wordplay.
'clamour' becomes 'cry' (clamour can mean to cry or yell).
'to include' indicates putting letters inside.
'lively' is an anagram indicator (letters get livened up or moved around).
'tune' is an anagram of 'entu'.
'cry' going around 'entu' is 'CENTURY'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for century that I've seen before include "100 years" , "A lot of runs!" , "Period of time" , "One hundred years" , "lot of time" .)
