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.
tilde
noun. spike, horn
til(de)
adverb. like [that by] you
aikale
noun. peak
A word in The Etymologies of the 1930s glossed “a peak”, an abstract noun formation of ᴹQ. aika “sharp” (Ety/AYAK).
mintye
noun. peak
A word in the Declension of Nouns from the early 1930s glossed “peak” given as an example for the Quenya declension of nouns ending in -ye (PE22/44). It is probably a derivative of ᴹ√MIN “stand alone, stick out”.
Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
A correlative combination appearing in Demonstrative, Relative, and Correlative Stems (DRC) from 1948 (PE23/111), a combination of ᴹQ. ti “that by you” and ᴹQ. -l(de) “way”.
