Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
A word appearing as ᴱQ. pirin (pirind-) “thin rod, pin” in the Qenya Lexicon of the 1910s under the early root ᴱ√PIRI having to do with cylinders and spinning (QL/74).
Neo-Quenya: In 1959 Tolkien gave a new meaning to the root √PIR as “close eyes, blink, wink” (PE17/146), but I believe this was a transient idea; see that entry for details. As such, I use the Neo-Root ᴺ√PIR with its earlier meaning “cylinder” and would use this to salvage ᴺQ. pirin “thin rod, pin”.
