Make invalid's absorbing phrase open to debate (10)

Ross

I believe the answer is:

disputable

'open to debate' is the definition.

'make invalid's absorbing phrase' is the wordplay.
'make invalid' becomes 'disable'.
'absorbing' is an insertion indicator.
'phrase' becomes 'put' (putting is a kind of phrasing).
'disable' going around 'put' is 'DISPUTABLE'.

(Another definition for disputable that I've seen is " Open to argument".)

I've seen this clue in The Guardian.
