Depression grips woman climbing wondrous monument (7)
I believe the answer is:
pyramid
'wondrous monument' is the definition.
'pyramid' can be an answer for 'monument' (pyramid is a kind of monument). I'm unsure of the 'wondrous' bit.
'depression grips woman climbing' is the wordplay.
'depression' becomes 'dip' (dip is a kind of depression).
'grips' indicates putting letters inside.
'woman' becomes 'mary' (woman's name).
'climbing' says the letters should be written backwards (in a down clue, letters climb up).
'dip' enclosing 'mary' is 'dimaryp'.
'dimaryp' reversed gives 'PYRAMID'.
Can you help me to learn more?
(Other definitions for pyramid that I've seen before include "old monument" , "something ancient in the sand?" , "Monumental Egyptian structure" , "A 3D shape" , "ancient monument" .)
