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.
rakta-
verb. to pile, hoard, amass, collect
rakta-
verb. to stretch out, reach
A verb appearing as ᴱQ. rakta- “stretch out, reach (intr.)” in the Qenya Lexicon of the 1910s under the early root ᴱ√RAHA “stretch forward” (QL/78).
Neo-Quenya: A later iteration of this root is ᴹ√RAK “stretch out, reach” from The Etymologies of the 1930s, so I think this verb can be retained as ᴺQ. rahta- “to stretch out, reach”, slightly modified to fit later Quenya phonology. Helge Fauskanger used such a modified verb in his NQNT (NQNT).
rakta
noun. arm
sorakta-
