The spelling of the word "more additory" may seem confusing, but it actually follows the rules of English phonetics. The first syllable "mo" is pronounced as /mɔː/, which is a variant of "more" in British English. The second syllable "re" is pronounced as /r/, followed by the suffix "-additory," which means "tending to add or increase." When pronounced in its entirety, "more additory" sounds like /mɔːr əˈdɪtəri/, and refers to something that has a strong tendency to add or augment something else.
