Angry comments in which one word leads to another (10)

I believe the answer is:

crosswords

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

'which one word leads to another' is the definition.
I can't tell whether this defines the answer.

'angry comments' is the wordplay.
'angry' becomes 'cross' (cross can mean annoyed or angry).
'comments' becomes 'words' (I can't justify this - if you can you should give a lot more credence to this answer).
'cross'+'words'='CROSSWORDS'

'in' acts as a link.

Can you help me to learn more?

(Another definition for crosswords that I've seen is " which call for solutions".)

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