Greetings
Ways, gestures and expressions for hello
The moment of hello is loaded: it sets the register for everything that follows and carries information about status, familiarity, and belonging.
Greetings include spoken words, titles, physical gestures, and the sequence of who greets whom first. They tell people how to place each other, what kind of relationship this is, and how the interaction is likely to go. Getting a greeting wrong, using the wrong form of address, missing a physical gesture, or greeting in the wrong order, can create awkwardness that lingers.
Formality, hierarchy, and familiarity all shape greetings, but so do gender, age, region, and the specific context (street versus office versus home). What looks like a single cultural norm is usually a layered set of situations, each with slightly different expectations.
