Comments on subclassification

Catalan Sign Language [cata1241], Valencian Sign Language [vale1251], Spanish Sign Language [span1263] (including Galician) clearly form a tight-knit family lexicostatistically ( Parkhurst, Stephen and Diane Parkhurst 2006 , Josep Quer and Laura Mazzoni and Galini Sapountzaki 2010: 98 , Carmen Cabeza-Pereiro and Silvia Iglesias-Lago 2015: 729 ). Venezuelan Sign Language [vene1237] has a historical connection and also belongs to this family ( Williams, Holly and Elizabeth Parks 2012 ):9. This family has an independent history ( Carmen Cabeza-Pereiro and Silvia Iglesias-Lago 2015 ):730-731 and (contra Henri Wittmann 1991: 282 ) is not related to LSF, at least not so that it can be traced lexically ( Parkhurst, Stephen and Diane Parkhurst 2006 ):22, nor to Lengua de Señas Mexicana ( Parkhurst, Stephen and Diane Parkhurst 2006 ):22.
