The girl appears in trepidation (3)

I believe the answer is:

ida

'the girl' is the definition.

'in trepidation' is the wordplay.
'in' indicates the answer is hidden within the clue.
'IDA' is hidden within 'trepidation'.

'appears' acts as a link.

(Other definitions for ida that I've seen before include "Stagey princess" , "Poetic princess" , "Name of girl or mountain" , "Mountain in Crete" , "Woman" .)

I've seen this clue in The Globe and Mail.
