Small organ is pitched (5)
I believe the answer is:
slung
'pitched' is the definition.
The answer and definition can be both to do with contact as well as being past participle verbs.
Maybe you can see an association between them that I don't see?
'small organ' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'organ' becomes 'lung' (lung is a kind of organ).
's'+'lung'='SLUNG'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for slung that I've seen before include "Thrown; suspended loosely" , "Threw out" , "Hurled" .)
