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 noun appearing as ᴹQ. karaste “making, manufacture, construction” in the Quenya Verb Structure of the 1940s, a combination of kar- “do, make, build” with the general action verbal suffix -ste (PE22/110).
Neo-Quenya: In Tolkien’s later writing, this verbal suffix became -sta (PE22/137), so I would update this noun form to ᴺQ. carasta “making, manufacture, construction”, which aligns nicely with the later verb carasta- “to build”.
