Bring, brang, brung.

Yesterday I heard someone non-ironically say the word thunk. As in think, thank, thunk.

Now granted he wasn't a native speaker, and it's an easy mistake to overgeneralize your way right into if you're not a native speaker. But I'm definitely adding it to my list of non-native speakerisms. I'm starting to track patterns from non-native speakers of different linguistic backgrounds and I'm noticing some interesting stuff that surely has ramifications for ESL curricula and software. I'm undertaking a project of documenting what I'm finding right now, since I have some ideas for applications of the work.
