The spelling of the word 'more nonobligatory' uses the prefix 'non-', meaning 'not', followed by 'obligatory', meaning 'required'. The additional 'more' emphasizes the level of non-obligation. In IPA phonetic transcription, it would be written as /mɔr ˌnɑnəˈblɪɡəˌtɔri/, with stress on the second syllable of 'obligatory'. While the word may seem lengthy and complex, its meaning is clear: something that is not required, but perhaps recommended or optional.
The term "more nonobligatory" does not have a specific etymology, as it is a combination of two English words: "more" and "nonobligatory".
"More" is derived from the Old English word "māra", which means "greater in amount, quantity, or degree". It has been in use since the 12th century and has remained relatively unchanged in meaning.
"Nonobligatory" is formed by adding the prefix "non-" to the word "obligatory". "Non-" is a prefix that indicates negation or absence, while "obligatory" comes from the Latin word "obligātus", meaning "to bind". Therefore, "nonobligatory" means "not required, not mandatory, or not binding".
When combined, "more nonobligatory" simply means that something is not required to a greater extent or in a greater degree.
