something i think is hard to do and i sometimes struggle with is run on sentences. I usually will either have the wrong punctuation or none when there needs to be so this website seemed to help.

Run-ons, comma splices, and fused sentences are all names given to compound sentences that are not punctuated correctly. The best way to avoid such errors is to punctuate compound sentences correctly by using one or the other of these rules.

1. Join the two independent clauses with one of the coordinating conjunctions (and, but, for, or, nor, so, yet), and use a comma before the connecting word.
_________________________, and _________________________.
He enjoys walking through the country, and he often goes backpacking on his vacations.
2. When you do not have a connecting word (or when you use a connecting word other than and, but, for, or nor, so, or yet between the two independent clauses) use a semicolon (;).
__________________________;_____________________________.
He often watched TV when there were only reruns; she preferred to read instead.
or
__________________________; however,____________________.
He often watched TV when there were only reruns; however, she preferred to read instead.
So, run-ons and fused sentences are terms describing two independent clauses which are joined together with no connecting word or punctuation to separate the clauses.
