Coalescence is the occurrence of two different phonetic units at the same time. The DGS examples below show that an ix sign, which has a pronominal function, can either be produced sequentially with the following verb teach (a) or alternatively it can also be produced simultaneously with the same verb forming a coalescence (b).
a. ix3 teach
‘She/he teaches.’
b.
h1: teach
h2: ix3
‘She/he teaches.’
