High Quality Content by WIKIPEDIA articles! Textual variants arise when a copyist makes deliberate or inadvertent alterations to a text being reproduced. Some common alterations include the deletion, rearrangement, repetition, or replacement of one or more words when the copyist`s eye returns to a similar word in the wrong location of the original text. If their eye skips to an earlier word, they may create a repetition (error of dittography). If their eye skips to a later word, they may create an omission, or they may resort to performing a slight rearranging of words to retain the overall meaning without compromising the context. In other instances, the copyist may add text from memory from a similar or parallel text in another location. Otherwise, they may also replace some text of the original with an alternative reading. Spellings occasionally change. Synonyms may be substituted. A pronoun may be changed into a proper noun (such as "he said" becoming "Jesus said").
