Film legend good with excitable boar (5)
I believe the answer is:
garbo
'film legend' is the definition.
The definition suggests a singular noun which matches the answer.
'good with excitable boar' is the wordplay.
'good' becomes 'g' (abbreviation).
'with' means one lot of letters go next to another.
'excitable' is an anagram indicator (I've seen this in other clues).
'boar' with letters rearranged gives 'arbo'.
'g'+'arbo'='GARBO'
Can you help me to learn more?
(Other definitions for garbo that I've seen before include "Greta . . . . ., film star who wanted to be alone" , "Swedish film star who wanted to be alone" , "Famous film actress" , "Reclusive film star" , "Swedish actress who wanted to be alone" .)
