Solemnizate is a rare word that means "to solemnize" or "to make solemn." Its pronunciation is /ˈsɒləmnɪzeɪt/, with stress on the second syllable. The word's spelling follows the common pattern for verbs ending in -ize, which is to add -ate to the stem of the word. In the case of solemnize, the stem is solemn, which comes from the Latin word sollemnis. This type of spelling is known as a back-formation, where a new word is derived from an existing one by removing an affix.
