need help on italicized portion of the sentence?

1.The weather remaining turbulent, we will postpone our canoe trip.

remaining or turbulent

if the remaining turbulent,will be postpone our canoe trip and i think its prepositional phrase with a gerund?

Please do yourself a favor and read over what you posted. It makes no sense.

Use proper capitals, etc.

am i right?

okay and the question is asking what is the grammar function of the italicized words or phrase

so did i get it right??

Which words are italicized?

I'd start the sentence with "If" -- how will you rephrase if you start with that word, too?

1.The weather remaining turbulent, we will postpone our canoe trip. <~~That's your original sentence, right? And you don't have to rephrase it?

There is no preposition (and therefore no prepositional phrase) in that sentence.

so that's not the grammatical structure of it? but doesn't it have a gerund in it?

The original sentence is strange. It's not completely phrased.

The main clause is fine: "...we will postpone our canoe trip."

That stuff at the beginning has a participle in it ("remaining"), but it doesn't modify anything in the main clause. To be correct, the sentence should read like this: If the weather remains turbulent, we will ...

But as it is, badly written as it is, I guess you'd have to say that "remaining" is a participle that modifies "weather."

so it would be a past or present participle?

okay thank you here's the next one 2.Although her personality had not changed at all, Megan looked quite different. i know its not a adjective clause

What is italicized?

not changed at all is italicized

That's part of a verb phrase in the dependent clause.

these are the choices that it can be

adverb clause
infinitive phrase
past participial phrase
elliptical clause
adjective clause

If this is italicized, then it's an adverb clause:

Although her personality had not changed at all

HOWEVER if only the words you gave above are italicized, there is no answer in that list.

okay and the next one is 3.Put the sizes on the uniforms while sorting them out. and the italicized is sorting them out,can only be

adverb clause
infinitive phrase
past participial phrase
elliptical clause
adjective clause

Now it's your turn. What do you think it is?

elliptical clause ?

"sorting them out" = not a clause

A clause must have a subject and a verb.

infinative

Now you're just guessing.
