is come to a peak

[JerrySmile]

Is this possible?

The feeling of excitement over what would happen then is come to a peak.
with an old-fashioned touch over the straight:
The feeling of excitement over what would happen then is at a peak.

I'm aware that "is come" is 19C and earlier, and that most would use today "has come," but in present day language the usage is different:

"is come" shows state
"has come" shows recent evolution

What I want to express is that "presently it is at a peak level" and I wonder if "is come," with all its old-fashioned connotations, could be used for that.

Thanks.

Emotions are running high / at fever pitch sounds more natural to me - context will indicate which emotions.

Both The feeling of excitement over what would happen then is come to a peak.
and
The feeling of excitement over what would happen then is at a peak.
seem to mix tenses confusingly.

The following are also possible:

The feeling of excitement over what would happen then has reached a peak.

The feeling of excitement over what would happen then is peaking.

[Edwin F Ashworth]

I'd prefer

The feeling of excitement over what would happen then had reached a peak.

or

The feeling of excitement over what will happen next has reached a peak.

(Though I could perhaps imagine a contrived scenario where the original tenses etc might work.)

I agree, Edwin. Your version #2 greatly improves on all the others.

Unlike Edwin, I'm not bothered by the mixture of tenses.

Like Edwin and Erik, I am bothered by the unusual collocation "come to a peak". It simply sounds odd, and their suggestions are all improvements.

The collocation with "come to" that most readily springs to mind is "come to a head".

If we take that collocation, I can see no semantic difference between

• Things have come to a head.
• Things are come to a head.

As you point out, however, "are/is come to" is now rare and possibly archaic.

"is come" shows state
"has come" shows recent evolution

I don't believe that your distinction holds, primarily because of the fundamentally perfective meaning of the present perfect. The whole notion of the present perfect relates to a present state. The notion of development would only be stressed by an appropriate adverbial phrase of time (e.g. "over the past weeks").

It's not that unusual in reference to beating egg whites. :)
