A root in The Etymologies of the 1930s glossed “give” with derivatives ON. yanta- “give” and ᴹQ. Ariante “Day-bringer” (EtyAC/YAN²). Tolkien marked this entry with a “?”, and elsewhere in The Etymologies he derived ᴹQ. anta-/N. anna- “give” from ᴹ√ANA (Ety/ANA¹), so I suspect this root was a transient idea.
