The noun {'op} is given as "some, an unknown or unspecified quantity".

I just realized that there's no rule against using the {'op} with {puS}/{law'}, thus specifying whether this "unknown quantity is of few or of many".

'op Duj puS vIjem

I detect an amount of ships which is of an unknown quantity (as far as their exact number is concerned), but I sense that they're few

The question now would be, whether we could apply directly the {law'}/{puS} to the {'op}; but I think that although there's no rule against it, it would sound rather strange to say {'op puS Duj} since that could sound like "ships of few/several unspecified quantities".

On the other hand though, perhaps we *could* say {'op vItlh} for "a high/great unspecified quantity". However, the question then would be what noun we could place the {'op vItlh} on; because the nouns that play well with {vItlh} i.e. the nouns that are "measurable or quantifiable but not necessary countable" don't sound that good with {'op}:

{'op Do}

a speed of unspecified quantity

(this sounds strange to me)

{'op vItlh Do}

a speed of high/great unspecified quantity

(this sounds equally strange to me)

On the third hand though, perhaps we *could* use the {'op vItlh} "a high/great unspecified quantity" with nouns which are countable:

{'op Duj}

some ships

(sounds fine to me)

{'op vItlh Duj}

ships of high/great unspecified quantity

(sounds equally fine to me)

Go figure.
