Nothing loth, about to take on a new daily (7)
I believe the answer is:
readily
'nothing loth' is the definition.
I can't judge whether this definition defines the answer.
'about to take on a new daily' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'to take on' says to put letters next to each other.
'a new' indicates an anagram.
'daily' is an anagram of 'adily'.
're'+'adily'='READILY'
Can you help me to learn more?
(Other definitions for readily that I've seen before include "Promptly and without difficulty" , "Without hesitation" , "in a willing manner" , "Willingly, quickly" , "Without difficulty or delay" .)
