Likely to order blue pails (9)
I believe the answer is:
plausible
'likely' is the definition.
(synonyms)
'order blue pails' is the wordplay.
'order' is an anagram indicator.
'blue'+'pails'='bluepails'
'bluepails' anagrammed gives 'PLAUSIBLE'.
'to' acts as a link.
(Other definitions for plausible that I've seen before include "Seemingly true" , "Reasonable on the face of it" , "Credible" , "easy to swallow" , "likely" .)
