A plant in the form of a glove (6)
I believe the answer is:
lovage
'a plant in' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how one could define the other.
'form of a glove' is the wordplay.
'form of' is an anagram indicator (another form of the same letters).
'a'+'glove'='aglove'
'aglove' is an anagram of 'LOVAGE'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for lovage that I've seen before include "F" , "Parsley relative - a glove (anag)" , "Herb and salad plant" , "Salad plant from a glove?" , "Salad plant from southern Europe" .)
