Thank you for your help.
Are they all grammatical? 'Yet' seems to be placed at the end of a sentence. What about #2?
They are all correct and common.
Yes, all four sentences are grammatically correct. The placement of "yet" in these sentences can vary depending on the speaker's preference or the desired emphasis.
In sentence 1, "It wasn't dark yet," the word "yet" is placed after the verb "dark." This sentence implies that it is not currently dark, but it will become dark in the future.
In sentence 2, "It wasn't yet dark," the word "yet" is placed after the verb "wasn't." This sentence conveys the same meaning as the first sentence, but with a slightly different word order. Both sentences 1 and 2 are commonly used and convey the same idea.
In sentence 3, "It was already dark," the word "already" is used instead of "yet." Here, "already" is placed before the adjective "dark" to indicate that the darkness has already occurred at the time being referred to.
In sentence 4, "It was dark already," the word "already" is placed after the adjective "dark" for emphasis, but the overall meaning is the same as sentence 3.
So, to answer your question, while "yet" is often placed at the end of a sentence, it can also be placed before or after different parts of the sentence to convey the same meaning.
