Roger slipped out of bed to consider a fresh approach (7)
I believe the answer is:
regroup
'consider a fresh approach' is the definition.
I can't tell whether this definition defines the answer.
'roger slipped out of bed' is the wordplay.
'slipped' indicates anagramming the letters.
'out of bed' becomes 'up' (synonyms).
'roger' is an anagram of 'regro'.
'regro'+'up'='REGROUP'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for regroup that I've seen before include "Come together again" , "Reorganise troops" , "Organise again after a defeat" , "Get together again after being defeated" , "Get back into position" .)
