Clap new rent arrangement (7)
I believe the answer is:
pattern
'arrangement' is the definition.
(thesaurus)
'clap new rent' is the wordplay.
'clap' becomes 'pat' (I am not sure about this - if you are sure you should believe this answer much more).
'new' indicates anagramming the letters.
'rent' is an anagram of 'tern'.
'pat'+'tern'='PATTERN'
Can you help me to learn more?
(Other definitions for pattern that I've seen before include "Stencil" , "Example; decorate" , "Blueprint, design" , "Ornamentation" , "Model to imitate" .)
