Thread:User talk:CodeCat/PGmc prepositions and adverbs/reply

There were adverbs ending in *-ê, and they're attested clearly in Gothic, Old Norse and Old English (but Old High German and Old Saxon have only *-ô from what I can tell). But I'm not sure about the adverbs with -an-. They don't have -anē in Gothic like you'd expect, instead they have -ana, which must have a different origin. Gothic -ana can reflect *-anō, *-anē, *-anǭ or *-anai. We'd have to compare the descendants in other languages to see which of those matches best. We'd also need to find a plausible etymology for them; most likely the ending is a fossilised case ending, so we'd have to identify which one.
