The '''zero-width non-joiner''' ('''ZWNJ''', {{IPAc-en|z|w|ɪ|n|dʒ}}; rendered: {{Not a typo|{{kbd|&#8204;}}}}; [[HTML entity]]: {{kbd|&amp;zwnj;}} or {{kbd|&amp;#8204;}}) is a [[non-printing character]] used in the computerization of [[writing system]]s that make use of [[Typographic ligature|ligatures]].  For example, in writing systems that feature initial, medial and final letter-forms, such as the [[Persian alphabet]], when a ZWNJ is placed between two characters that would otherwise be joined into a ligature, it instead prevents the ligature and causes them to be printed in their final and initial forms, respectively. This is also an effect of a [[Space (punctuation)|space character]], but a ZWNJ is used when it is desirable to keep the characters closer together or to connect a word with its morpheme.

The ZWNJ is encoded in [[Unicode]] as {{unichar|200C|ZERO WIDTH NON-JOINER|html=}}.
