There seem to be certain phrases that only non-native speakers of a language use, regardless of their native tongue. The one I’ve seen the most is using ‘doubt’ as a noun: “I have a doubt about X.” I’ve seen it used in my bioinformatics class, and I’ve seen it on the Google Summer of Code mailing lists.
Is there a name for these constructions? From a native speaker’s point of view, they’re awkward, but might seem idiomatic to non-native speakers? Pidgin + Idioms = Pidioms, perhaps? (Google has no meaningful results for that word.)
