I have to go now.

This problem has been lingering in my mind for years. How to analyse it ?

have = verb ? ( if have is verb, then ' to go ' is noun phrase and ' now ' is adverb ) ? If this is the case, then ' now' as an adverb can't modify a ' noun phrase ' but modify the have Emotion: stick out tongue . That analysis is a little awkward thenEmotion: smile What do you think ?

have to = auxiliary and go is the verb ?

Just change it into "I must go" - then it's easier to analyze: "go" here is the full verb that is in its infinitive and follows the modal auxiliary must - without to! I have to go: "have to" is the substitute form for "must", "go" again is the full verb in its infinitive. "Have to" here is a fixed expression, and therefore "to" is actually part of the following infinitive form of the full verb, not a preposition.

  • If it was a preposition, usually a Gerund would have to follow (as eg.
  • in "I look forward to seeing you).

It's a matter of doing things in the right order.

The noun phrase in "I have to go now" is "to go now", not merely "to go".

Basically, "now" is an adverb, which modifies the verb "to go", and THEN, after having been so modified, the whole lot gets converted to single a noun phrase.

Just because ' have ' and ' to ' are always stuck together. So to say that ' have ' is the verb and ' to go now ' is the ' noun phrase ' means we break up the ' have ' and ' to ' for analysis. ?

From Pem's point of view, if ' go ' is the verb, then ' have to ' is an auxilliary verb but it is not mentioned as such in any grammar book. That's why it baffles me
