In the phrase "¿Cómo se dice?" which translates to "How do you say?" in English, the word "do" in English doesn't have a direct counterpart in Spanish. Instead, Spanish constructs questions differently. Here’s how it breaks down:

In Spanish, questions often don't require the auxiliary verb "do" like in English. The verb form "dice" (from "decir," meaning "to say") combined with "se" (a reflexive pronoun here indicating a general statement or question) creates the meaning.

So, "¿Cómo se dice?" directly translates to "How is it said?" or more naturally in English, "How do you say?"
