I was asked a question that started with is but had a period at the end. The person told me it was ok as long as there was intent meant.

Is too!
We use a lot of devices when talking. One device is to omit words because that somehow emphasizes something. My example above has no subject, because the subject is already known, and the verb "is" is incomplete because I imply a repetition of a verb already stated. So my position is emphasized by only stating the contrary parts. Any sort of omission like that is called "ellipsis". You will hear that word occasionally, usually referring to three periods which are placed to indicate that a word or a thought has been unspoken.
Here is a book that lists about 900 figures found in the bible. It is almost the only work in the subject for the last two thousand years:
