Definition
A retainer is something that holds or keeps something else in place. Think of it as a support structure that prevents movement or change. In orthodontics, it's a device worn after braces to maintain the alignment of teeth. In a legal context, it's a fee paid to secure the services of a lawyer. βοΈ Unlike a one-time payment, a retainer ensures ongoing availability. In both cases, it serves to keep something in its desired position or state. π¦·
