Phrase: ... I hope I have been of some help.

Hi Amy,
I wonder if the following clause is right: “… I hope I have been of some help.”
I can’t help feeling that something is missing at the end of the sentence.
Thanks,
Irene

What’s missing?

Hi Irene

No, as Mister M indicated, nothing is needed on the end of that sentence. It is possible to add (optionally) a number of things after the noun ‘help’, but your sentence is fine the way it is.
.

Are you thinking of things such as:

I hope I have been of some help to you/them/your family/the company, etc?

You could add one of those, or quite a few others, but the context normally doesn’t require the addition of such.

Thanks Molly and Amy,
Irene
