The gentleman with the spectacles inside is a N. African (4)
I believe the answer is:
moor
'african' is the definition.
(I've seen this before)
'the gentleman with the spectacles' is the wordplay.
'the gentleman' becomes 'mr'.
'with' means one lot of letters goes inside another.
'the spectacles' becomes 'oo' (I've seen this in other clues).
'mr' placed around 'oo' is 'MOOR'.
'inside is a n' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for moor that I've seen before include "Berth, tie up" , "Upland tract - eg Othello" , "Open land covered with heather and bracken" , "Secure boat to fixed object" , "Make fast a boat - open tract of rough ground" .)
