A word appearing as ᴱQ. piukka “blackberry” in the Qenya Lexicon of the 1910s, an elaboration of ᴱQ. pio “berry” (QL/61, 74). This word was also mentioned in the contemporaneous Poetic and Mythological Words of Eldarissa and Gnomish Lexicon (PME/74; GL/64).

Neo-Quenya: I’d adapt this word as ᴺQ. piuca “blackberry” for purposes of Neo-Quenya, since a diphthong cannot precede a double-consonant in Quenya as Tolkien’s conceived it in his later writings.
