From Proto-Italic *iðei or Proto-Italic *ifei with iambic shortening, from the pronominal stem Proto-Indo-European *éy, whence also is. In the first case cognate to Sanskrit इह (iha, “here”), Proto-Indo-Aryan *Hidʰá (“here”), Avestan (idā, “here, in the same way”), in the latter recalls the ins.pl. suffix *-bʰi. The same suffix is present in ubi ~ ubī.
ibi or ibī (not comparable)
