have to have...

Hi Everyone,

I got into a bit of a bit of pickle the other night with the following sentence:

' How many lattes would Sam have to sell to have sold more than Cathy did last week?'

One of my students wanted to know why we say - have to sell to have sold.

I think this is to do with a conditional?
How could I best explain why we can say this phrase?

Many thanks

" In the first part, "have to" is the "have to" of requirement/obligation. "would" is expressing an imagined or hypothetical situation. " is a valid question by itself.

  • " In the first part, "have to" is the "have to" of requirement/obligation.
  • "would" is expressing an imagined or hypothetical situation.
  • " is a valid question by itself.
  • In the second part, "to have sold" is looking back from the imagined point at which the sales target is reached.
  • That is why the perfect infinitive "to have sold" is chosen.

There are two parts to this:

"How many lattes would Sam have to sell / (in order) to have sold more than ..."

In the first part, "have to" is the "have to" of requirement/obligation. "would" is expressing an imagined or hypothetical situation. "How many lattes would Sam have to sell?" is a valid question by itself.

In the second part, "to have sold" is looking back from

Many thanks GPY! Great explanation.

I can see that your second choice is also correct - 'have to sell to sell'. Wouldn't we need a comma in-between 'sell, to sell' though?

I forgot about the perfect infinitive. I hope my student will get this next week. I told the class that I'd let them know next week. I did explain it then and there, but told them I'd check to make sure I give

There is no proper grammatical justification for a comma. To me, a comma would look like a kind of fudged attempt to deal with the awkwardness of the repetition.

Ok. I guess it also rides on natural space intonation within the sentence. I would naturally take a breathe in the same way you've bolded the second to sell...

I think a native speaker has the rhythm of the sentence, whereas a non native would find this difficult perhaps?

Thanks GPY.

It is not unnatural to make a small pause there in speech. However, for me this do
