Target female officer commanding us (5)
I believe the answer is:
focus
'target' is the definition.
(I've seen this before)
'female officer commanding us' is the wordplay.
'female' becomes 'f' (common abbreviation).
'officer commanding' becomes 'oc' (this could be a standard abbreviation which I don't know about).
'f'+'oc'+'us'='FOCUS'
Can you help me to learn more?
(Other definitions for focus that I've seen before include "Maximum clarity of an idea" , "Point at which light rays converge or diverge" , "Where light-rays meet" , "Concentration of attention or energy" , "Concentrate on something, perhaps with camera" .)
