Reconstruction:Proto-Celtic/tungeti

Etymology
A verb infamous for its complicated origin. There are two major theories on its origin:
 * A modern theory derives the verb from a suppletive conflation of a nasal-infix present *lungeti from and a preterite derived from . The initial t- outside the present would thus come from analogy with the preterite. This theory dismisses a connection with.
 * An older, more traditional theory supposed descent from, ne-infixed verb from the root , with semantic divergence (i.e. to “take (an oath)”); compare 🇨🇬, especially in the figurative meanings “affect; enchant”, 🇨🇬 and 🇨🇬. The o-grade in Old Irish however would be unexplained.
