Felt like scratching (6)
I believe the answer is:
itched
'felt like scratching' is the definition.
The answer and definition can be both to do with perception as well as being past participle verbs.
Maybe you can see a link between them that I can't see?
This is all the clue.
Can you help me to learn more?
(Other definitions for itched that I've seen before include "had urges" , "Was keen" , "Was impatient (to do something)" , "Longed (to do something)" , "Was in need of a scratch" .)
