The spelling of the word "wildlives" may seem odd at first glance, but it actually has a phonetic basis. The first syllable "wild" is pronounced as the IPA symbol /waɪld/, while the second syllable "lives" is pronounced as /laɪvz/. The two syllables together form a portmanteau word, combining the idea of wild animals with the plural form of "lives". While unconventional, this spelling is a creative and memorable way to express the idea of multiple animals living in the wild.
Wildlives does not have an established etymology as it is not a common or widely recognized word. It appears to be a combination of the words wild and lives, suggesting a plural form of wildlife.
