The terms "appetizers," "hors d'oeuvres," and "finger foods" often overlap but have some subtle differences:

1. Hors d'oeuvres: This French term translates to "outside of the work" or "apart from the main meal," and refers to small, savory bites typically served before dinner, usually at a cocktail hour or during a reception where guests might not necessarily be seated. They are elegant and designed to be eaten in one or two bites, often presented on trays by servers or placed on a display.
2. Canapes: Small pieces of bread, crackers, or croutons with various things on top are another category of food served before a meal.
3. Appetizers: These are eaten before a meal - literally food eaten to pique the appetite. Appetizers are also a popular option to serve with a drink to quell the hunger that can emerge with a beverage.
4. Finger Foods: This is a more casual term that encompasses any small food items meant to be eaten directly with the hands, without the need for utensils. Finger foods can be served as both hors d'oeuvres or appetizers depending on the setting. They are ideal for informal gatherings or parties. These may include things like sliders, tea sandwiches, empanadas
