Concisely expressive of compassion about the hurt head (5)
I believe the answer is:
pithy
'concisely expressive' is the definition.
'pithy' can be an answer for 'expressive' (thesaurus). I am unsure of the 'concisely' bit.
'compassion about the hurt head' is the wordplay.
'compassion' becomes 'pity' (pity is a kind of compassion).
'about' indicates putting letters inside.
'head' says to take the initial letters.
The first letter of 'hurt' is 'h'.
'pity' enclosing 'h' is 'PITHY'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for pithy that I've seen before include "Terse, powerful (speech)" , "Short and sweet" , "Cogent" , "Concise and meaningful" , "succinctly expressed" .)
