Q1: What is the most natural reply when someone greets me with "What's up?"
A1: The most common native responses are "Not much," "Nothing much," or "All good, how about you?" Native speakers treat "What's up?" as a greeting rather than a literal inquiry into their current activities.
Q2: Is "Good night" ever used as a greeting in English?
A2: No. Unlike the Spanish *buenas noches*, which serves as both an arrival salutation and a departure farewell after dark, the English phrase "good night" is exclusively a farewell. To greet someone in the evening, always say "Good evening."
Q3: How should I greet someone whose gender or title is unknown in an email?
A3: Avoid outdated phrases like "To Whom It May Concern" whenever possible. Use "Dear [First Name] [Last Name]" if the full name is visible, or opt for role-based openers such as "Dear Hiring Team" or "Greetings to the Editorial Board."
