There seems to be a lot of that going around.
"When you visited the museum last week" is a dependent clause, so it is a sentence fragment. It does not express a complete thought on its own and needs to be connected to an independent clause to form a complete sentence.
A sentence fragment is a group of words that is punctuated like a sentence but is incomplete because it lacks a subject, a verb, or both. It does not express a complete thought and does not form a complete sentence.
The result is a sentence fragment. These fragments do not express a complete thought or idea and require additional information to form a complete sentence.
an intentional fragment is a form of writing where you use one word as a sentence. this creates "drama" and makes the word stand out.
YES - it doesn't tell you what happens next - eg - I picked a beautiful flower.
The term "very sorry for having done wrong" is a sentence fragment (there is no subject to form a complete sentence). The abstract noun in the sentence fragment is "wrong" a word for a concept.
It is a sentence. It is a declarative sentence also because it's giving a demand.
I'd say it was a fragment. 'The fog rolled in' seems to need something extra to form a sentence - for example... The fog rolled in quickly - The fog rolled in across the bay
It could be either. 'Sit!' as an imperative form of the verb to sit (an instruction given to a dog, for example) is a sentence in its own right. Sit can also be just one word in a sentence, for example 'I asked you not to sit there.' In that case it would be a fragment.
Yes, "walk slowly" is a fragment because it does not contain a subject and a verb to form a complete sentence. It lacks the necessary elements to express a complete thought.
A phrase or clause written as a sentence but lacking an element, as a subject or verb, that would enable it to function as an independent sentence in normative written English.
Yes. You can end a sentence with "am I" as is shown here: "I'm not that mean, am I?". I'd think that it'd normally be in the form of a question with some sort of punctuation (like the comma in the example) separating it from the main body of the sentence. Just make sure that you don't do something like this: "I'm not that mean. Am I?". In that sentence "Am I" is a sentence fragment.
