"Adneural" is a word that refers to something being situated next to or adjoining a nerve. Phonetically, this word can be divided into three syllables: "ad" /æd/, "neu" /nu/, and "ral" /ɹəl/. The "ad" prefix means "near" or "next to", while "neu" means "nerve". The suffix "ral" indicates that the word is an adjective, meaning it modifies a noun. Thus, "adneural" is a precise term to describe something in close proximity to a nerve.
