Usage

And is thru in the dictionary? Thru is not listed as a standard word in this dictionary, meaning that language users don’t view it as an accepted word and don’t use it regularly with a standard meaning. Instead, thru is an informal variant of through that is particularly common in the United States. An informal variant is a term used in informal situations but not recognized as acceptable by most language users. You wouldn’t use thru in formal or semiformal situations, but you might see it used in informal contexts or in the compound term drive-thru. Note: Just because a word isn’t considered a standard word in the dictionary doesn’t necessarily mean it’s “not a word.” Some people may use it, and if enough people start using it regularly, it may be added to the dictionary.
