Looks like a hack :smile: If you go down the route of modifying the sentence, I would suggest something lighter like adding commas to make it clear what the subject is: “The head-template, followed by the ellipsis …, indicates that …”

I have a line before that:

The third line says that a template can have the form @racket[(head-template ...)]. This will construct a syntax object representing a list. The @tt{head-template} followed by the ellipsis @racket[...] indicates that the elements of the constructed lists are created from 0 or more @em{head templates}.

So the intention was to bring the … into attention.

Then rocketnia’s “combination” seems more accurate

Or use the commas differently. I strongly suggest: “The, head-template followed by, the ellipsis … indicate,s that …”

If you want to focus on the ellipsis, why not make it the subject? Like, “The ellipsis indicates that the elements of the constructed list are created from 0 or more instances of the preceding head template.”

If it is important to mention the head-template, it’s possible to have “The ellipsis following the head-template indicates…”. That’s only necessary if there are multiple ellipses though.

Or, to keep the sequential order: “Preceded by the head template, the ellipsis … indicates …”
