Rows in forms that will please the eye (11)
I believe the answer is:
shapeliness
'will please the eye' is the definition.
I can't judge whether this defines the answer.
'rows in forms' is the wordplay.
'rows' becomes 'lines' (row can mean a line of things).
'in' is an insertion indicator.
'forms' becomes 'shapes' ('shape' can be a synonym of 'form').
'lines' placed into 'shapes' is 'SHAPELINESS'.
'that' is the link.
Can you help me to learn more?
(Other definitions for shapeliness that I've seen before include "Pleasing form" , "Attractive form" , "Visually attractive quality" , "Attractive and well-proportioned quality" .)
