What is "strikethrough"

n. A typographical presentation of words with a horizontal line through their center. This is an example. vb. (context nonstandard English) To partly obliterate text by drawing a continuous line through the centre thereof, usually to indicate the deletion of an error or obsolete information.

Strikeout is a typographical presentation of words with a horizontal line through their center, resulting in this effect. Contrary to censored texts, the words remain readable. This presentation signifies one of two meanings. In ink-written, typewritten, or other non-erasable text, the words are a mistake and not meant for inclusion. When used on a computer screen, however, it indicates recently deleted information. It can also be used deliberately to imply a change of thought (as in epanorthosis).
