Unusually attentive but hesitant (9)

I believe the answer is:

tentative

'hesitant' is the definition.
(I've seen this before)

'unusually attentive' is the wordplay.
'unusually' is an anagram indicator.
'attentive' anagrammed gives 'TENTATIVE'.

'but' acts as a link.

(Other definitions for tentative that I've seen before include "Exploratory - hesitant" , "Experimental" , "Conjectural" , "Exploratory, unconfident" , "Attentive in hesitant manner" .)

I've seen this clue in The Irish Independent.
