You're probably familiar with inherent, the adjective meaning "part of the constitution or natural character of something," but were you aware of its less common relative inhere? This verb looks like it could be a back-formation of inherent (a back-formation is a word created by removing a prefix or suffix from an existing word), but usage evidence of the two words makes it difficult to tell for sure. Both inhere and inherent date to the late 16th century and are derived from the Latin verb inhaerēre ("to inhere"), which was itself formed by combining in- with haerēre, a verb meaning "to adhere."
