Underline the consequence of overwork (6)
I believe the answer is:
stress
This clue might be a double definition.
'underline' is the first definition.
(I've seen this before)
'consequence of overwork' is the second definition.
'stress' can be an answer for 'consequence' (thesaurus). I am unsure of the 'of overwork' bit.
'the' is the link.
Can you help me to learn more?
(Other definitions for stress that I've seen before include "State mental or emotional strain" , "Particular emphasis" , "nervous tension" , "Physical or mental over-exertion" , "Strain or accentuate" .)
