In which sentence is the italicized word used correctly?

A) The principle welcomed the students back from vacation.
B) We visited the Capitol building during our visit to Washington.
C) The students were instructed to use capitol letters on the form.
D) My friend said that we should not participate, as it is a matter of principal.

A or d?

To determine which sentence uses the italicized word correctly, let's examine the sentences one by one.

In sentence A, the word "principle" is used correctly, referring to a basic truth, law, or rule.
In sentence B, the word "Capitol" is used correctly, referring to the building where a legislative body meets, such as the United States Capitol.
In sentence C, the word "capitol" is used incorrectly. The correct word in this context should be "capital" instead, referring to an uppercase letter.
In sentence D, the word "principal" is used correctly, referring to a person who holds a high position, such as the head of a school.

Therefore, the correctly used word is in sentence A: "The principle welcomed the students back from vacation."

No. Neither of those is correct. Please do not post this again.
