Doctor around one article shows indecision (6)
I believe the answer is:
dither
'indecision' is the definition.
(I've seen this before)
'doctor around one article' is the wordplay.
'doctor' becomes 'dr' (abbreviation).
'around' indicates putting letters inside.
'one' becomes 'i' (Roman numeral).
'article' becomes 'the' (the definite article in English).
'i'+'the'='ithe'
'dr' enclosing 'ithe' is 'DITHER'.
'shows' is the link.
(Other definitions for dither that I've seen before include "State of high agitation" , "Agitate indecisively" , "perturbation" , "Be in two minds" , "Hit red in order to vacillate" .)
