Make into one tune I organised (5)
I believe the answer is:
unite
'make' is the definition.
The answer and definition can be both related to change as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'one tune i organised' is the wordplay.
'organised' indicates anagramming the letters.
'tune'+'i'='tunei'
'tunei' with letters rearranged gives 'UNITE'.
'into' is the link.
Can you help me to learn more?
(Other definitions for unite that I've seen before include "Join together, become allies" , "fuse" , "pool resources" , "Link" , "Join together, merge" .)
