Protecting dress, mother getting on rubber glove (8)
I believe the answer is:
marigold
'rubber glove' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'protecting dress mother getting on' is the wordplay.
'protecting' is an insertion indicator (inserted letters are held or protected).
'dress' becomes 'rig' (rig is a kind of dress).
'mother' becomes 'ma' (ma can mean mother).
'getting on' becomes 'old' ('getting on a bit' means 'old').
'ma'+'old'='maold'
'rig' going into 'maold' is 'MARIGOLD'.
Can you help me to learn more?
(Other definitions for marigold that I've seen before include "Yellow or orange flower" , "The flower has a gold rim, oddly" , "floral item" , "Orange daisy" , "Composite plant" .)
