Felt sick and unable to talk (6)
I believe the answer is:
gagged
'felt' is the definition.
The answer and definition can be both related to bodily activities as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'sick and unable to talk' is the wordplay.
I cannot quite see how this works, but
'sick' could be 'gag' (gagging is a kind of sicking) and 'gag' is present in the answer.
The remaining letters 'ged' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for gagged that I've seen before include "Silenced" , "Struggled for breath or prevented from speaking out" , "Muffled or retched" , "Not allowed to speak out" .)
