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!
The word for “zebra” in the Gnomish Lexicon of the 1910s was raibrog or ribrog with a feminine variant raibros, a combination of G. raib “striped” and G. brog “horse” (GL/64).
Neo-Sindarin: I’d adapt this word as ᴺS. raebroch for purposes of Neo-Sindarin, using the later word S. roch for “horse”.
