I'm not sure I'd want to use a highly irregular (probably scribal error?) as one of our examples. I'd think it'd be best to stick to conventional orthography.

I'm not sure this is a good example. אורב is probably a conventional noun here rather than something that might otherwise be taken in a verbal sense.

Might it be more accurate to say a nominative meaning?

"...and both are definite."

I think it would be much easier to just translate this "ambushers" which would help to not lose the sense of the Hebrew as well as bring clarity to the translation.

I think its actually done with "O'".... rather than with "oh"

It seems to me that you could put this in bold as well, making it an even stronger example.

I'm not sure if these types are worth mentioning?

I think this is actually an example of "Already mentioned".

It seems to me that each of these headings should include a one or two sentence description/explanation. The naked headings could be understood in several different ways when the grammar is being translated into other languages. Being more specific is better, I think, especially concerning a particle is frequently used as the definite article.

As I changed the direction of this article somewhat, this section may no longer be nencessary.
