In which Amy regularises plurals

Amy will often talk about someone's "feets".

I suppose this is because she knew the irregular plural "feet" from fairly early on, and then when she later acquired the regular plural marker -s, she tacked it on for good measure, thus marking the plural twice.

It reminded me of Klingon children talking about ngopmey ("plateses", or something like that—tacking on the regular plural marker -mey to the suppletive plural ngop "plates" of jengva' "plate"). Or, for that matter, Dutch children talking about kinderen and eieren, which have two plural markers, too: -er-en. (As does English child-r-en; compare German Kinder with only the -er plural marker.)

Deer

I used to think that English deer = German Reh.

However, apparently English deer = German Hirsch, and German Reh is specifically English roe deer. (English red deer, for example, is a German Rothirsch.)

Ah well; I was never very good at telling apart all those antlery animals in the first place, in any language.

Then you have elk meaning something different on both sides of the Atlantic: in North America it's a German Wapiti, while in Europe it's what Americans call a moose and Germans an Elch. Confusion!
