Organised moving fifteen to house 101 (9)
I believe the answer is:
efficient
'organised' is the definition.
The answer and definition are different parts of speech. However, past participle verbs and adjectives can sometimes mean the same thing.
'moving fifteen to house 101' is the wordplay.
'moving' indicates an anagram.
'to house' indicates putting letters inside.
'101' becomes 'CI' (roman numerals).
'fifteen' is an anagram of 'effient'.
'effient' placed around 'ci' is 'EFFICIENT'.
Can you help me to learn more?
(Other definitions for efficient that I've seen before include "Performing with little wastage" , "Working in a well-organised and competent way" , "Effective in doing what is required" , "Not wasting energy" , "Businesslike" .)
