There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

Middle Primitive Elvish

srō

root. *east

A root appearing in a rejected page of roots from the Quenya Verbal System (QVS) written in 1948 (PE22/127), possibly as a variant of √RŌ/ORO that Tolkien introduced to explain S. rhûn “east” after he decided initial r- did not become rh- in Noldorin/Sindarin; see the entry on S. rhûn for discussion.

yan

root. give

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.
