Support, taking a better grip? (6)
I believe the answer is:
uphold
'support' is the definition.
(upholding is a kind of supporting)
'a better grip?' is the wordplay.
'a better' becomes 'up' (I can't justify this - if you can you should believe this answer much more).
'grip?' becomes 'hold' (synonyms).
'up'+'hold'='UPHOLD'
'taking' acts as a link.
Can you help me to learn more?
(Other definitions for uphold that I've seen before include "Support a decision or belief" , "'Support, the law say (6)'" , "Confirm or support, say a verdict" , "Champion" , "Support, maintain" .)
