 Examples of "plene scripta" appear frequently in classical Hebrew texts, and copyists are obliged to copy them unchanged, to ensure that biblical or other sacred texts are written with universal conformity.The expression "plene scriptum" ( "yater", "excess"), sometimes simply described in Hebrew as מלא ("malé", "full"), is often used in contrast with defective scriptum ( "ḥaser", deficient), the latter implying a word in which a letter that is normally present has been omitted.Together, "plene" and "defective scripta" are sometimes described using the Hebrew phrase "haser ve yater" ().
