Early Primitive Elvish
tun+tǝ
root. *see, notice, perceive
sehe
root. *see
þehe
root. *see
{ᴱ√TUNU >>} ᴱ√TUN + Tǝ or Kǝ appeared as unglossed root in the Qenya Lexicon of the 1910s with derivatives like ᴱQ. tunke “bright, witty, smart” and ᴱQ. tunta- “see, notice, perceive” (QL/95). I think it is worth positing a Neo-Root ᴺ√TUNTU to salvage some of these early words having to do with general perception.
