The ability to understand others gets first person back on track at the end of the day (7)
I believe the answer is:
empathy
'the ability to understand others' is the definition.
I can't judge whether this defines the answer.
'first person back on track at the end of the day' is the wordplay.
'first person' becomes 'me' (first-person pronoun).
'back' says the letters should be written backwards.
'on' says to put letters next to each other.
'track' becomes 'path' (synonyms).
'at the end of' suggests the final letters.
The final letter of 'day' is 'y'.
'me' reversed gives 'em'.
'em'+'path'+'y'='EMPATHY'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for empathy that I've seen before include "Ability to identify with another's feelings" , "Psychological identification" , "Shared emotion" , "Ability to identify mentally with another person" , "Pay them (anag.)" .)
