Reconstruction talk:Proto-Italic/duō

It says that it is indeclinable. I thought duo (as well as ambo) preserve the original PIE dual inflection?

@RubixLang Doesn't look like it; the Latin declension doesn't look anything like expected from the reconstructed PIE dual (which don't even have many distinct case forms, nor any separate feminine forms, see w:Proto-Indo-European nouns#Case endings) and appears to be a relatively recent innovation, possibly dating to as recently as pre-literary Archaic Latin (only attested in a couple of inscriptions from the mid-first millennium BC). --Florian Blaschke (talk) 16:59, 26 October 2019 (UTC)
