A word appearing as ᴱQ. kalar “lettuce” in Early Qenya Phonology of the 1920s derived from primitive ᴱ✶karase (PE14/70), where the final s became z and then r, after which the medial r dissimilated to l.

Neo-Quenya: The dissimilations in later Quenya were different, with the medial r preventing the z from becoming r and instead dissimilating it back to s (PE19/73). As such, I would adapt this word as ᴺQ. caras “lettuce” for purposes of Neo-Quenya, which also has the advantage of differentiating it from Q. calar “lamp”. Note that the stem for this word would also be caras- rather than the usual carar- due to the same dissimulative forces.
