Organised moving fifteen to room 101 (9)
I believe the answer is:
efficient
'organised moving' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs sometimes define each other.
'fifteen to room 101' is the wordplay.
I cannot quite understand how this works, but
'101' could be 'ci' (roman numerals) and 'ci' is found within the answer.
an anagram of 'fifteen' is 'effient' which is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for efficient that I've seen before include "working economically at speed" , "Effective in doing what is required" , "Producing results with little waste of effort" , "Performing with little wastage" , "Working well with little waste" .)
