Moezelaar (m)
(with) definite article: deany person who plays some kind of bagpipe (&c.)
Variant spelling, according to WNT mentioned in Kiliaan, in which I have not encountered this term, however (➺ Moeseler); NB: Unfortunately, the reference to Kiliaan mentioned in WNT is inactive (yet) as a link [ws, Nov. 2021].
