Through and through or thru and thru

Through and through is an adverb and means to do something completely, in any manner possible. A good synonym is thoroughly. Sometimes this phrase is used as an adjective with regard to bullet wounds. A through and through is something that goes in one side of something or someone and comes out the other side, as opposed to staying inside the body or object.

Thru is an alternative spelling to through and has its own listing in the dictionary. Though some European dictionaries list it as mainly being used in North America. This alternate spelling is used somewhat in the form thru and thru, but it is vastly outnumbered in usage with through and through. Most of the instances of it we found were in lesser quality publications or extremely informal settings, like the comment section of articles.

One exception seems to be in headlines. We saw one or two instances when the shorter spelling was preferred in a headline to keep the word count down. The downside to this strategy is that the article automatically seems less formal and more commonplace.

The discussion of the differences between through and thru are discussed more in depth in another article.
