Bare infinitive after except

Question

According to these two links link1 link2, we should use bare infinitive after “But, than, except”

But I have read the below sentence somewhere

She had no choice except to wait for the next train.

So is this sentence wrong?

Answer 1

EXCEPT takes a matrix-licensed complement: its complement is licensed by the verb in the main or matrix clause. In this case, the main verb is HAVE. HAVE allows a to-infinitival clause complement with a deontic sense, as in:

I had to wait for the next train

Since the complement of EXCEPT is licensed by HAVE and HAVE allows a to-infinitival complement, the sentence is grammatical.
