BDSM Terminology 101: A Comprehensive Glossary

This glossary is here to help make BDSM terminology feel less confusing and a lot more approachable. It breaks down common terms, acronyms, roles, and phrases you will see in kink spaces, without assuming you already know everything or have years of experience.

Kink terms changes, communities grow, and new conversations pop up all the time, so this glossary will be updated regularly as new terms come up and understanding evolves.

Whether you are just starting out, coming back after some time away, or simply trying to make sense of a word you keep seeing, this space is meant to support curious, informed, and fully consensual exploration at your own pace.

Capitalization Structure
and
Respect Language

You might notice that in some BDSM spaces, people play with capitalization, and it is not a typo. It is a respect thing.

In many power exchange dynamics, Dominant titles like Sir, Miss, Mistress, Daddy, Mommy, or a chosen honorific are often capitalized as a way to show authority, respect, or earned position within that relationship.

On the flip side, submissive identifiers like submissive, slave, babygirl, babyboy, little, or pet are often written in lowercase to reflect humility, surrender, or the intentional power imbalance that both people have agreed to.

This is not a rule, and it is definitely not universal BDSM terminology. Some people use it all the time, some only with their partner, and some not at all. Like most things in kink, it only matters if the people involved say it matters.

For this article, I am keeping capitalization standard, so it is easier to read and beginner friendly. You may still see respect-based capitalization used elsewhere on the site when it fits the dynamic or the tone of the content.

Some examples you may see include capitalizing certain pronouns or collective language, such as Y/you, W/we, or U/us. This is often used by submissives to show respect or acknowledgment of authority when referring to their Dominant, their dynamic, or a shared power structure.

For example, someone might capitalize You when addressing their Dominant directly or use U/us to represent a bonded dynamic rather than two equal individuals.

Like title capitalization, this kind of language choice is highly personal and dynamic specific. Some people use it intentionally in writing but not speech, some only in private communication, and others not at all. It is less about correctness and more about meaning between the people involved.
