Could anybody tell me how do we ask them politely?

I don't understand why can not omit "of" here....

***** NOT A TEACHER *****


Hello, Polyester:

Here is some information that may interest you.

1. The ring is of gold.

2. "of gold" is a prepositional phrase.

a. It is adjectival. That is, it describes "the ring." ("is" is a linking verb.)

3. It would not be accurate to say "The ring is gold," for it is NOT gold.

a. It is "of gold." That is to say, it is golden (an adjective).

ONLY my ideas (based on the information above).

1. "Tom was nice." (adjective that describes "Tom.")
2. "Tom was a teacher." (noun that describes "Tom.")
3. "Tom was helpful." (adjective that describes "Tom.")
4. "Tom was service." (The noun "service" canNOT describe "Tom" -- a fact that other posters have told us.)
5. "Tom was of service" = (something like) No. 3.

Not all our services are suitable for the prospects.

I think it should be 'Our services are available only to eligible clients' according to post#14.

3. It would not be accurate to say "The ring is gold," for it is NOT gold.

a. It is "of gold." That is to say, it is golden (an adjective).

If the following definition is correct, 'gold' is also an adjective which means 'made of gold'.

Hi Mathew

Prospect refers to a prospective client.

'Prospect' refers to a 'likely customer'── quoted from http://www.macmillandictionary.com/dictionary/british/prospect_1#prospect_1__6

I don't think they are customers because they are asking for trade finance from you.
