Did exam last Monday and got cranky (5)
I believe the answer is:
testy
'cranky' is the definition.
(I know that cranky can be written as testy)
'did exam last monday and' is the wordplay.
I cannot really see how this works, but
'exam' could be 'test' (synonyms) and 'test' is located in the answer.
A single letter 'y' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'got' is the link.
Can you help me to learn more?
(Other definitions for testy that I've seen before include "bad temper" , "Irascible" , "Grumpy" , "Ratty" , "Quick to anger" .)
