Improper comma use, and… Freaking run-on sentences.
I need to give a class in all three grades about run-on sentences ASAP because my students just don’t know when to end a sentence.
EXAMPLE: Yesterday, it was so hot, i went to the store to buy some ice cream, they didn’t have any ice cream, I was mad, disappointed, hungry, I screamed at the lady working behind the counter because there was no ice cream, when I came home my mom said she bought some chocolate candy, I ate that, I was happy.
I think that’s probably why they do it. Their first language is Spanish, and sentences tend to be longer in Spanish and are considered grammatically correct.
Depends on the sentence and it’s structure. I am a master of making extremely long sentences, but having them perfectly grammatically correct. So with those they are technically fine, just difficult for some people to read.
If it’s a compound or complex sentence, yes. But you should use coordinating conjunctions to connect two independent clauses, and a relative pronoun to connect an independent clause with a dependent one.
