Straightforward description of blonde old fogey (4-3-6)
I believe the answer is:
fair-and-square
'straightforward description' is the definition.
'fair and square' can be an answer for 'description' (I have seen 'Honest description' mean 'fair and square' so perhaps 'description' could also mean 'fair and square'). I am unsure of the 'straightforward' bit.
'blonde old fogey' is the wordplay.
'blonde' becomes 'fair' (similar in meaning).
'old' becomes 'and' (I am not sure about this - if you are sure you should believe this answer much more).
'fogey' becomes 'square' (I have seen 'Old fogey' mean 'square' so perhaps 'fogey' could also mean 'square').
'fair'+'and'+'square'='FAIR-AND-SQUARE'
'of' is the link.
Can you help me to learn more?
(Other definitions for fair-and-square that I've seen before include "On the level" , "Honestly, straightforwardly" , "Legitimately" , "Honest" , "All above board" .)
