A new name asks the reader to remember someone. If five names arrive before anyone acts, that request can become difficult. Examine the first appearance of one character and ask what gives the name a place in the scene.
Attach the name to a useful relationship
The reader may need to know that the person owns the shop, is waiting for the narrator, or has interrupted a conversation. Choose the relationship relevant now. A full biography can wait until the scene creates a reason to want it.
Try placing the name beside a clear action. “Mara held the lift door” gives the reader something to follow. This is an illustrative sentence, not a requirement that every introduction use the same pattern.
Check the surrounding names
Read the paragraph aloud and note how many unfamiliar people it introduces. Could one remain “the driver” until they become important? Could a later sentence carry a detail currently crowded into the introduction?
Finally, ask a reader who the new character is in relation to the scene. You are testing orientation, not whether they memorised every trait. A successful introduction gives enough information to keep reading and leaves room for the character to become more particular through what they say and do.
