Irritated at delay when I am seeing a doctor (9)
I believe the answer is:
impatient
'irritated at delay' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs can occasionally mean the same thing.
'i am seeing a doctor' is the wordplay.
'i am' becomes 'I'm' (contraction).
'seeing a doctor' becomes 'patient' (I can't explain this - if you can you should believe this answer much more).
'im'+'patient'='IMPATIENT'
'when' is the link.
Can you help me to learn more?
(Other definitions for impatient that I've seen before include "Fidgety" , "Job wasn't" , "Keen" , "fed up with waiting time?" , "Over-eager" .)
