-`Replacement_Group` | `string` | Replacement events can also be considered taking a more liberal approach: that is, replacement events can, in some cases, be reconstructed to higher-order protolanguages or to multiple protolanguages in an area, either when the apparent exceptions seem to be possibly due to subsequent borrowing or when the “replacement event” could be viewed as a single areal spread across multiple languages or language groups. The “conservative” replacement events listed here are grouped into “liberal” events via matching values for the `Replacement_Group` column. If there is no discrepancy between the more conservative and the more liberal approaches, an event will be in a replacement group of its own.
