dither

I'm a little stuck... Click here to teach me more about this clue!

'be undecided' is the definition.
I can't tell whether this definition defines the answer.

'doctor about one article' is the wordplay.
'doctor' becomes 'dr' (abbreviation).
'about' indicates putting letters inside.
'one' becomes 'i' (Roman numeral).
'article' becomes 'the' (the definite article).
'i'+'the'='ithe'
'dr' placed around 'ithe' is 'DITHER'.

'as' is the link.

Can you help me to learn more?

(Other definitions for dither that I've seen before include "Vacillate, be undecided" , "Display of nerves" , "perturbation" , "Be undecided and somewhat agitated" , "indecision" .)
