• *dāti (with dereduplication)

From Proto-Indo-European *dédeh₃ti. Cognate with Latin dō and Lithuanian dúoti.

*didāti^[1][2]

1. to give

• According to KPV and Darling, this verb was originally reduplicated.^[1][2] In Insular Celtic (and Gaulish as well, if the imperative da is of any indication, unless that imperative is from a root aorist^[3]), the reduplication was lost, yielding *dāti, but signs of a reduplicated present persisted in Celtiberian; but even there, the imperative lost reduplication.
• This verb had a reduplicated preterite in the simplex, as attested in Celtiberian and Gaulish. However, this preterite formation may be replaced with an s-preterite when this verb was prefixed, as Gaulish and Old Irish show.
• It can be difficult to distinguish derivatives of this verb and derivatives of *didīti (“to put, place”).
