Just beginning to go back for a bit of exercise (3)
I believe the answer is:
jog
'a bit of exercise' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?
'just beginning to go back' is the wordplay.
'beginning to' indicates taking the first letters.
'back' says the letters should be written backwards.
The initial letter of 'just' is 'j'.
'go' reversed gives 'og'.
'j'+'og'='JOG'
'for' is the link.
Can you help me to learn more?
(Other definitions for jog that I've seen before include "Trot" , "Run for fun" , "Run at a leisurely pace" , "Slow run" , "Reminder" .)
