Nonspinosity is a rare word that means the condition or quality of lacking spines. The IPA phonetic transcription of the word is /ˌnɑnˌspaɪnɑˈsɪti/. The "non" prefix indicates negation, "spino" refers to spines, and "-ity" is a suffix indicating the state or quality of. Therefore, the spelling is using the common prefixes and suffixes in English to form a specific and precise meaning. While not a frequently used term, it is a great example of how English words are built from smaller components.
