Take some time next to counter in New York - it’ll help you get your words right (12)
I believe the answer is:
spellchecker
'take some time next to counter in new york it'll' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'help you get your words right' is the wordplay.
I cannot quite understand how this works, but
'help' could be 'checker' (checker is a kind of help) and 'checker' is found within the answer.
'words' could be 'spell' (I have seen 'Magic words ' mean 'spell' so perhaps 'words' could also mean 'spell') and 'spell' is found within the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for spellchecker that I've seen before include "Means of spotting misprints" , "Dumbledore, for example" , "Might one be confused by form from" , "Computer device which scrutinises text" .)
