Point to a rule of material significance (4)
I believe the answer is:
lawn
'material significance' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'point to a rule' is the wordplay.
'point' becomes 'n' (N is an example).
'to a' says to put letters next to each other (I've seen this in other clues).
'rule' becomes 'law' (law is a kind of rule).
'n' put after 'law' is 'LAWN'.
'of' is the link.
Can you help me to learn more?
(Other definitions for lawn that I've seen before include "sleeves composer?" , "Fine cotton or grass garden" , "Patch of grass in the garden" , "Grass-covered ground" , "Grassy area" .)
