'first,i must go shopping,then i have to decide what to fix for dinner.'
is this a CORRECT SCENTENCE ,COMA SPLICE OR A FUSED SCENTENCE?
Writeacher
There should be two sentences there.

Which type do you think it is?

The comma after "first" is not needed. Otherwise it's correct. This is a compound sentence. It is not correctly capitalized, though!
Reed
And, yes, it could be two sentences instead of a compound sentence. Do read the link Writeteacher posted for you.
Writeacher
The word "then" is not a coordinating conjunction. Therefore, this cannot be a compound sentence.

Did you figure out which it is, javeria?
javeria
i think its a fused scentence
Reed
"then" is a subordinate conjunction, as are "before", "if", "because", etc.

One could write this sentence several ways:

I must go shopping before I have to decide what to fix for dinner.

I must go shopping; I have to decide what to fix for dinner.

I must go shopping. Then I must decide what to fix for dinner.

I think it's okay as it stands, too.
