The spelling of the word "Erative" is quite unusual, but it can be easily understood with the help of the IPA phonetic transcription. The word is pronounced as [ˈɛrətɪv], with the stress on the first syllable. The use of the letter 'e' followed by the letter 'r' suggests that the word is derived from the Latin verb "ero" (meaning "to be" or "to exist"). The suffix "-ative" means "having the quality of," thus "Erative" could mean "having the quality of being."
