A
A/B/O (Alpha/Beta/Omega) — A trope with hierarchical dynamics that comes in different flavors: (1) pack hierarchy and scent bonding common in shifter romance, and (2) the fuller Omegaverse with heats, ruts, knotting, and mpreg common in sci-fi and paranormal. Some books blend both. See also Omegaverse.
Adequate Grovel — When the love interest actually earns forgiveness through meaningful action, not just a sad face and "I'm sorry." The bar is low but some books still limbo under it.
Aftercare — Post-intimacy care and comfort, especially in kink contexts. Also: what readers need after finishing an emotional book.
Age Gap — Significant age difference between love interests. Usually specified in years because "she's 25 and he's 38" hits different than "she's 45 and he's 58."
Alpha — Multiple meanings: (1) In Omegaverse: the designation that experiences ruts, can knot, and is biologically driven to mate with Omegas. (2) In shifter romance: the pack leader, top of the hierarchy. (3) In general romance: a dominant, protective, take-charge hero personality type. These can overlap—a shifter Alpha who's also an Omegaverse Alpha—but not always.
Alpha-hole — An alpha hero who's actually just... kind of an asshole. Sometimes reformed, sometimes not. Reader mileage varies wildly.
Angst — Emotional turmoil, pain, suffering. The good stuff. "High angst" means bring tissues.
ARC (Advance Reader Copy) — Free early copy given to reviewers before publication. Not to be sold, Karen.
B
Backlist — An author's previously published books. Where you go when you've devoured their new release and need MORE.
BDSM — Bondage, Discipline, Dominance, Submission, Sadism, Masochism. A spectrum of kink dynamics in romance, ranging from "light restraints" to "there's a contract."
Beta — Three different meanings depending on context: (1) In Omegaverse: the "neutral" designation—no heats, no ruts, no knotting, often the "normal" humans in the world. (2) In shifter pack hierarchy: a second-in-command to the Alpha. (3) In publishing: a beta reader who gives feedback on a manuscript before publication. Context is everything.
Beta Hero — A softer, gentler hero archetype. Think: supportive, emotionally available, not trying to alpha his way through problems. Often underrated.
Bite/Claiming Bite — In shifter and Omegaverse romance: a bite (usually on the neck/shoulder) that marks a mate as taken and often creates a permanent bond. Not just a hickey—this one's magical/biological and means something.
Billionaire Romance — Rich hero, usually with a tragic backstory to justify the wealth feeling relatable. Private jets, penthouses, emotional unavailability (at first).
Binge Read — Consuming an entire series in one sitting. Sleep is for people who don't need to know what happens next.
Bond/Bonding — Connection between mates that goes beyond normal relationships. (1) In shifter romance: often instinctual recognition, may involve mental/emotional links. (2) In Omegaverse: scent bonding, usually sealed through claiming bites during heat. (3) In fantasy: soul bonds, magic bonds, various mystical connections. Strength and permanence vary by world.
Black Cat — A personality type: mysterious, aloof, probably says "I hate everyone except you" energy. Often paired with golden retriever.
Black Moment — The point where everything falls apart before the HEA. Maximum despair. Also called "the breakup" or "why is this author hurting me."
Body Positive — Romance that celebrates all body types without making weight loss or "fixing" a character's body part of the narrative. Bodies are not problems to solve.

Brat Tamer — The character who handles the brat. Usually patient until they're not.

C
Chaos Goblin — A character who creates havoc wherever they go. Usually affectionate, often exhausting, always entertaining.
Cinnamon Roll — A pure, sweet, too-good-for-this-world character. Soft. Precious. Must be protected. Can still be spicy in the bedroom.
Claiming — (1) In shifter/paranormal romance: marking a mate as taken, often through a bite that leaves a permanent mark. (2) In Omegaverse: similar, often involves biting during heat/rut that creates a permanent bond. (3) In general romance: possessive declaration that someone is "yours." Intensity varies by subgenre.
