How to Say Welcome in Spanish: the Complete Guide to Greetings, Formal Protocol, and Etiquette
Because bienvenido functions grammatically as a verbal adjective, it must agree in gender and number with the person or group being addressed. The identity of the speaker does not change the ending. The identity of the listener controls everything.
Addressing an individual male requires bienvenido. Welcoming an individual female demands bienvenida. If a real estate agent greets a female executive stepping into a Madrid penthouse, the agent says bienvenida, regardless of whether the agent is male or female.
Plural forms follow standard grammatical rules. A group consisting entirely of women receives bienvenidas. A group of men, or any mixed-gender group containing at least one male, takes the masculine plural: bienvenidos. When welcoming an audience to a specific venue or event, the phrase adapts smoothly to bienvenidos al (short for a el) when the noun is masculine, such as bienvenidos al hotel, or bienvenidos a la for feminine spaces, like bienvenidos a la conferencia.
Language academies like the Real Academia Española (RAE) maintain standard masculine plural dominance for mixed groups, though modern corporate communication and international events frequently employ explicit pairings like bienvenidos y bienvenidas to maintain direct social inclusivity.
