Subnotation is spelled sʌbnoʊˈteɪʃən (suhb-noh-tey-shuhn). This word is formed by combining the prefix "sub-" (meaning "below" or "under") with the word "notation" (meaning "a system of written symbols used to represent something"). The IPA phonetic transcription shows that the stress is on the second syllable, "noh," and that the "-tion" ending is pronounced as "-shun." Subnotation refers to a secondary or implied meaning, typically in written or symbolic communication.
