Like one part of speech attorney recalled, insignificant (9)

I believe the answer is:

adnominal

'like one part of speech' is the definition.
(adnominal means attached to a noun)

'attorney recalled insignificant' is the wordplay.
'attorney' becomes 'D.A.' (District Attorney).
'recalled' is a reversal indicator.
'insignificant' becomes 'nominal' (as in a nominal fee).
'da' back-to-front is 'ad'.
'ad'+'nominal'='ADNOMINAL'

I've seen this clue in The Times.
