Reconstruction:Proto-Indo-Iranian/Hwárdʰati

Uncertain.

Some forms to compare are:

• Per Schindler, a metathesised verb from Proto-Indo-European *h₁lewdʰ- (“to grow”), making it a doublet of *Hráwdʰati (whence Sanskrit रोध॑ति (ródhati, “to grow”)).
• Per Cheung, perhaps semantically influenced by Proto-Indo-European *h₃erdʰ- (“to increase, grow”), making it a doublet of *Hr̥dʰnáwti and *Hr̥dʰyáti.
• Proto-Balto-Slavic *rádīˀtei (“to give birth”).
• Proto-Slavic *verdъ (“wart, growth”).
