Usage notes

 * Despite being grammatically masculine, -iwr only refers solely to males when a coordinate female term is available, for example, vs . When no female term is in current use, the grammatically masculine term in -iwr is neutral as regards biological sex, for example . Use of the explicitly female suffix  is old-fashioned outside of certain established terms.
