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.

Qenya 

alta

adjective. large, great in size

A word in The Etymologies of the 1930s under the root ᴹ√ÁLAT “large, great in size”, so probably of similar meaning (Ety/ÁLAT). It had a prefixal form alat- as in ᴹQ. Alataire “Great Sea”, a name appearing in The Etymologies and nowhere else.

verb. to (make) grow

A rejected verb for “grow” or “make grow” in The Etymologies of the 1930s based on the root ᴹ√GAL “grow, thrive” (EtyAC/GAL², GAL(AS)).

alat-

prefix. large, great in size

faire

noun. radiance

úra

adjective. large

A word in The Etymologies of the 1930s glossed “large” derived from the root ᴹ√UR “wide, large, great”, itself a revision of ᴹ√UR “be hot” (Ety/UR).

Neo-Quenya: Since √UR “heat” was restored in Tolkien’s later writings, I would not use the adjective úra for “large”.
