Credit one point to run after various kinds of copy of the text (10)
I believe the answer is:
typescript
'copy of the text' is the definition.
'typescript' can be an answer for 'copy' (thesaurus). I am unsure of the 'of the text' bit.
'credit one point to run after various kinds' is the wordplay.
I cannot really see how this works, but
'credit' could be 'cr' and 'cr' is located in the answer.
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'point' could be 'pt' (abbreviation for point) and 'pt' is present in the answer.
'kinds' could be 'types' (type is a kind of kind) and 'types' is present in the answer.
No letters remain.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Other definitions for typescript that I've seen before include "printed document" , "printed copy" , "Lines" .)
