In rhetoric, anthimeria or antimeria (from Ancient Greek: ἀντί, antí, 'against, opposite', and μέρος, méros, 'part'), means using one part of speech as another, such as using a noun as a verb: "The little old lady turtled along the road."
Other substitutions could include an adjective used as a noun, as in "She dove into the foaming wet," interjection as verb, as in "Don't aha me!"
The punctuation mark '/' was originally used to juxtapose related words or phrases, such as a 'friend/roommate', meaning that the referred person is both a friend and a roommate.
The symbol '/' (technically, named "virgule") is often pronounced 'slash', and now often used as a kind of conjunction or conjunctive adverb: "emergence of a new conjunction/conjunctive adverb (let alone one stemming from a punctuation mark) is like a rare-bird sighting in the world of linguistics: an innovation in the slang of young people embedding itself as a function word in the language".
[7] 'Slash' has been used to "link a second related thought or clause to the first" as well as simply "introduc[ing] an afterthought that is also a topic shift".
