DBA
Grammar usage guide and real-world examplesUSAGE SUMMARY
The word "DBA" is correct and usable in written English.
It is an acronym for "doing business as" and is often used in the context of stating a business's alternate or assumed name. Example: John Smith is the owner of a small bakery in town, known as "Sweet Treats Bakery." However, he also operates a food truck that he runs under the name "Smith's Sweets DBA." This allows him to have a separate brand and business entity for his food truck, while still being under his overall business umbrella.
