Fully ready to get me out of a rut, possibly (6)
I believe the answer is:
mature
'fully ready' is the definition.
'mature' can be an answer for 'ready' (thesaurus). I'm not certain of the 'fully' bit.
'me out of a rut possibly' is the wordplay.
'out of' is an insertion indicator (some letters on the outside of others).
'possibly' indicates an anagram.
'a'+'rut'='arut'
'arut' with letters rearranged gives 'atur'.
'me' placed around 'atur' is 'MATURE'.
'to get' acts as a link.
Can you help me to learn more?
(Other definitions for mature that I've seen before include "Fully grown and developed (6)" , "Fully-developed" , "Age" , "Grow older" , "sensible" .)
