Endless presents . . . it needs to change (10)
I believe the answer is:
persistent
'endless' is the definition.
(I've seen this before)
'presents it needs to change' is the wordplay.
'needs to change' indicates an anagram.
'presents'+'it'='presentsit'
'presentsit' is an anagram of 'PERSISTENT'.
(Other definitions for persistent that I've seen before include "fixed" , "Tenacious; constant" , "Lasting, prolonged" , "Pressing" , "Continual" .)
