What does it mean when you see the label brit. in a word’s dictionary entry?

a. the word is not considered part of standard english.
b. the word is not widely used today.
c. the word is used mainly in great britain, not in the united states.
d. the word is new to the dictionary.

The answer is indeed letter C. The word is used mainly in Great Britain, not in the United States.

Explanation:

Brit and US are geographical labels found in dictionary entries. They come in parentheses and are used to indicate where that word is mostly used. Thus, if the label Brit comes after a word, it means it occurs typically in British English - that may include other varieties, such as Australian English -, but not in American English. An example would be the informal word "bevvy", which refers to an alcoholic beverage. In a dictionary entry, we could find bevvy (Brit).

Geographical labels are also used to indicate that a certain way to spell a word belongs to one of the varieties of English as well. For example, the color gray has different spellings according to where it is used. Thus, we would find grey (Brit.) and gray (US) in a dictionary entry.
