Lengthened or extended (10)
I believe the answer is:
protracted
I believe this is a double definition.
'lengthened' is the first definition.
(protracting is a kind of lengthening)
'extended' is the second definition.
(I know that extended can be written as protracted)
(Other definitions for protracted that I've seen before include "Lengthy" , "Dragged out" , "Drawn-out" , "Lengthened out" .)
