Boringly spin around, lazily following current (9)
I believe the answer is:
insipidly
'boringly' is the definition.
Both the answer and definition are adverbs. Maybe you can see an association between them that I can't see?
'spin around lazily following current' is the wordplay.
'around' indicates anagramming the letters.
'lazily' becomes 'idly' (synonyms).
'following' says to put letters next to each other.
'current' becomes 'I' (physics symbol).
'spin' anagrammed gives 'nsip'.
'nsip'+'idly'='nsipidly'
'nsipidly' put after 'i' is 'INSIPIDLY'.
Can you help me to learn more?
(Other definitions for insipidly that I've seen before include "So as to have no definite flavour" , "In a vigourless manner" .)
