Is that a metaphor?

Not sure about this one, logic tells me it's a conjunction as in, however or but, when it introduces a lesser or negetive point about the subject.

eg. It looks great, but it uses a lot of petrol.

Anybody else want to try?

I'm not sure about this, it's just a guess - but maybe a coordinate conjunction connects two equal elements while a subordinate conjunction introduces an oblique sentence.

Examples:
1.) coordinate conjunction could be e.g. "and": Carl is drinking a coke and he is eating a potato.
2.) subordinate conjunction could be e.g. "because": Carl is sleeping because he is ill.

No, the first one doesn't sound logical. It sounds like sb who has real bad manners. What do you think?

LOL ... yes, that's on the top of everything ***

According to Michael Swan's "Practical English Usage":

1. Subordinating conjunction.- a conjunction (e.g. that, what, whenever) which connects a subordinate clause to the rest of the main clause. Example: He asked what I meant.

2. Co-ordinating conjunction.- a conjuction (e.g. and, but, or) that joins co-ordinate clauses.

3. Co-ordinate clause.- one of two cl

I think the examples are quite significant but number 2 hasn't got any. Maybe we would need more examples.

Hi Maj. Actually, the examples in (3) are also referred to (2). I just wanted to make clear what a co-ordinating clause was first, and not to leave anybody in limbo.

Oops! Sorry, I should've written "co-ordinate clause", not *co-***.
