Papa recalled row about opening of clothes drawer (6)
I believe the answer is:
pencil
'drawer' is the definition.
(something which draws)
'papa recalled row about opening of clothes' is the wordplay.
'papa' becomes 'P' (phonetic alphabet: alpha, bravo, charlie etc.).
'recalled' says the letters should be written backwards (to recall can mean to bring something back).
'row' becomes 'line' (as in a row of things).
'about' means one lot of letters goes inside another.
'opening of clothes' becomes 'c' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'line' going around 'c' is 'licne'.
'licne' in reverse letter order is 'encil'.
'p'+'encil'='PENCIL'
Can you help me to learn more?
(Other definitions for pencil that I've seen before include "A writing stick" , "__-sharpener" , "HB writer?" , "Writing implement with graphite centre" , "implement in case?" .)
