Despite this, tonal phenomena are conspicuously absent from most studies on language change, so that interest and progress in the understanding of the origins and evolution of suprasegmental contrasts lags behind that of segmental contrasts (Janda & Joseph 2003, Dockum 2019, Campbell 2021). Nevertheless, starting in the latter half of the 20th century, steady progress has been made in the investigation of tonogenesis, i.e. in the emergence of tonal contrasts. This research has identified various pathways for a language to acquire tonal contrasts from segments. Haudricourt’s (1954) model of tonogenesis in the so-called Sinospheric Tonbund (Matisoff 2001) connects the emergence of tonal contrasts with originally segmental material and processes of simplification of syllable structure. Similar progressions, from segmental contrast to tonal, can be observed in other languages and language families, such as Athabaskan (Kingston 2005), Mayan (see discussion in Bennett 2016, 497-499), Uto-Aztecan (Manaster-Ramer 1986; Guion et al. 2010), Punjabi/Northwest Indo-Aryan (Baart 2014; Evans et al. 2018), Malagasy (Howe 2017), and Afrikaans (Coetzee et al. 2018), among others. Prosodic contrasts can also give rise to tones, as in
