Titlo is an extended diacritic symbol initially used in early Cyrillic manuscripts, e.g., in Old Church Slavonic and Old East Slavic languages. The word is a borrowing from the Greek "", "title" (compare dated English tittle, see tilde). The titlo still appears in inscriptions on modern icons and in service books printed in Church Slavonic.
