verbWeak class 2to touch, pat, tapFrom Proto-Indo-European *teh₂g- (‘to touch’), either derived from a u-stem derivative of the root + *-ōną, or, if the alternative reconstruction *þakkōną is correct, inherited from Proto-Indo-European *th₂gnéh₂ti and thus formally cognate with Latin tangō (“touch”, verb). Further cognate with Ancient Greek τεταγών (tetagṓn, ‘having seized’), τάσσω (tássō, ‘arrange’) and Latin taxō (“touch, feel”, verb). Phonemically similar to Proto-Germanic *tēkaną (‘to touch’), and may even be related (see there for more)
