Apparently weak figure having quiet power around border (6)
I believe the answer is:
shrimp
'apparently weak figure' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'quiet power around border' is the wordplay.
'quiet' becomes 'sh' ('sh' is used to tell someone to be quiet).
'power' becomes 'p' (symbol in physics).
'around' is an insertion indicator.
'border' becomes 'rim' (both can mean an edge).
'sh'+'p'='shp'
'shp' placed around 'rim' is 'SHRIMP'.
'having' acts as a link.
Can you help me to learn more?
(Other definitions for shrimp that I've seen before include "colour?" , "Seafood" , "no giant" , "Raising of a siege" , "Small, weak person" .)
