Slovenian Sign Language (ysl-ysl) = 5 (Developing). Recognized language (2002, Law 96/02, Law on the Use of Slovenian Sign Language, ZUSZJ). Recognized language (2021, Constitution Article 62a), guarantees free use and development of Slovenian Sign Language, to be further regulated by law. Also guarantees for Italian SL [ise] and Hungarian SL [hsh] in some areas.
