Delayed changing stair carpet on landing essentially (14)
I believe the answer is:
procrastinated
'delayed' is the definition.
(procrastinating is a kind of delaying)
'changing stair carpet on landing essentially' is the wordplay.
'changing' is an anagram indicator.
'landing essentially' becomes 'd' (I can't justify this - if you can you should believe this answer much more).
'stair'+'carpet'+'on'='staircarpeton'
'staircarpeton' anagrammed gives 'procrastinate'.
'procrastinate'+'d'='PROCRASTINATED'
Can you help me to learn more?
(Other definitions for procrastinated that I've seen before include "Put off action" , "delayed" .)
