• This chart shows the diachronic spread of Proto-Indo-European and is based on the information available.
• It is intended to show the relative ages of the branches and is not to scale.
• Bold dates denote immediate genetic relationships with PIE. Other dates are for reference only.
• All dates are approximate mark the beginning (individualization) of a language.
• Eurasiatic is included to give plausible context, for there must be some parent language. The validity of the macro-family is not relevant.
