In an alphabetic writing system, a silent letter is a letter that, in a particular word, does not correspond to any sound in the word's pronunciation. In linguistics, a silent letter is often symbolised with a null sign U+2205 ∅ EMPTY SET, which resembles the Scandinavian letter Ø. A null or zero is an unpronounced or unwritten segment.
