Old man of vigour and energy can’t work after an hour (15)
I believe the answer is:
pithecanthropus
'old man' is the definition.
(I've seen this before)
'of vigour and energy can't work after an hour' is the wordplay.
I cannot quite see how this works, but
'of' could be 'o' and 'o' is found within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
'energy' could be 'e' (physics symbol as in E=mc2) and 'e' is found within the answer.
'work' could be 'pit' (pit is a kind of work) and 'pit' is found within the answer.
'an' could be 'a' and 'a' is found within the answer.
'hour' could be 'hr' (abbreviation) and 'hr' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for pithecanthropus that I've seen before include "Ancestor" , "apelike man" , "Old man" .)
