Trixes and Tresses, or: Return of the Grammar Nazi

Recently I stumbled upon the rarely used and, in my opinion, charming term aviatrix. As it always is with the twisted paths of language, it got me thinking (results may vary).

Clearly I had encountered a lady pilot, the fairer complement to an aviator. Of course it is well within my knowledge that nouns ending on -tor (when describing an acting male person) find their female pendant by substituting the ending with -trix⁽¹⁾. Terminatrix is a rather modern example, often referring to the “female” robot T-X from Terminator 3 (2003), although being around at least since 1995⁽²⁾.
