Sentences vs. Fragments

has a subject and a predicate

has a punctuation mark that ends the sentence (period, exclamation mark, question mark)

expresses a complete thought

may only have a subject and not a predicate or vice versa

does not have a punctuation mark to end the sentence

does NOT express a complete thought

sometimes, fragments will have a word in front of it that will make you wonder what will happen next

Example: When we got to our seat on the train,

You are probably wondering what happened when they got to their seat on the train

the word, "when", made it a fragment

take out the word, "when", and read the words aloud
