Poet Ovid is tense, no sex for him (5)
I believe the answer is:
odist
'poet' is the definition.
(someone writing odes)
'ovid is tense no sex for him' is the wordplay.
I cannot quite see how this works, but
'is' is present in the answer.
'tense' could be 't' (abbreviation used in many dictionaries) and 't' is found in the answer.
'no' could be 'o' (O resembles 0) and 'o' is found within the answer.
A single letter 'd' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for odist that I've seen is " Poet".)
