Continuing like this before long (4)
I believe the answer is:
soon
'before long' is the definition.
(I know that before long can be written as soon)
'continuing like this' is the wordplay.
I cannot quite see how this works, but
'like this' could be 'so' ('like so') and 'so' is present in the answer.
The remaining letters 'on' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for soon that I've seen before include "Willingly" , "Shortly" , "Early, in a short time" , "Presently" , "in a minute" .)
