1. I've not met with anyone differentiating katana and uchigatana, especially Japanese. Katana is a general term for single edge blade.
2. Lot of later uchigatanas were basically tachi blade in a uchigatana mount so length is not decisive.
3. Odachi very large tachi that explains things. Doesn't really but there seems to be no agreement as to what that length is and is it any different from nodachi (conveniently omitted).
4. "Mistranslation". "Tuck-to-side", "side tuck" or "side inserted" convey the meaning of the name and they don't stray from actual words used. No need for poetic interpretations.
5. Kodachi is another weird specimen I wasn't able to find much about nor would I know how it differs from wakizashi really. If anything small 'tachi' not 'dachi' though.
6. While 'polearm' is kinda ok there were somewhat similar weapons in Europe so might as well be more precise and call naginatas glaives (since spears are also polearms and there's even one spear/lance right under).
