“…As shown in Tables 1 and 2, Indonesian (Adelaar, 1992; Adisasmito-Smith, 2004; Batais, 2013; Lapoliwa, 1981; Soderberg & Olson, 2008) and Minangkabau (Adelaar, 1992; Almos, 2012; Erwandi, 2018; Medan et al, 1986; Zurmita et al, 2013) share 19 consonants: three bilabials /p, b, m/, six alveolars /t, d, s, n, r, l/, two post-alveolars /ʧ, ʤ/, two palatals /ɲ, j/, four velars /k, g, ŋ, w/, and two glottals /ʔ, h/. However, compared to Minangkabau, Indonesian has four additional consonants, namely /f, z, ʃ, x/, which are limited to foreign loanwords (as a result, they are placed in parentheses in Table 1).…”
