Times Review originally provided papers in three parts (6)

I believe the answer is:

trifid

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

'times review originally provided papers in three parts' is the definition.
I can't judge whether this definition defines the answer.

'times review originally provided papers' is the wordplay.
'originally' says to take the initial letters.
'provided' becomes 'if' (eg 'provided it's sunny' means 'if it's sunny').
'papers' becomes 'ID' (identification papers).
The first letters of 'times review' is 'tr'.
'tr'+'if'+'id'='TRIFID'

Can you help me to learn more?

(Another definition for trifid that I've seen is " Botanically divided into three lobes".)

I've seen this clue in The Sunday Times and The Times.
