verb. to fasten, tie

A verb in The Etymologies of the 1930s glossed “to fasten, tie”, under the root ᴹ√TAK “fix, make fast” (Ety/TAK). It is clearly based on an ancient causative form ✱taktā- “to make fixed/fast”, where the ancient k spirantalized and then vocalized and eventually produced the diphthong ae.
