The name of the herb "savory" is spelled thus everywhere, although the related adjective "savo(u)ry", like "savo(u)r", has a "u" in the UK. "Honor" (the name) and "arbor" (the tool) have "-or" in Britain, as mentioned above, as does the word "pallor". As a general noun, "rigour" has a "u" in the UK; the medical term "rigor" (sometimes ) does not, such as in "rigor mortis", which is Latin. Derivations of "rigour"/"rigor" such as "rigorous", however, are typically spelled without a "u", even in the UK. Words with the ending "-irior", "-erior" or similar are spelled thus everywhere.
