"Are big" does not have a specific dictionary definition as it is grammatically incorrect and incomplete. However, I can provide you with definitions for both "are" and "big" separately.
"Are" is the second person and plural form of the verb "to be." It is used to indicate that a subject is in a state of existence, identity, or condition. It is also used as an auxiliary verb in forming various tenses, voices, and moods.
"Big" is an adjective that describes something as being of significant size, magnitude, or extent. It refers to objects, ideas, or physical dimensions that exceed average proportions and often suggest ample space, considerable importance, strength, or influence. It can be used to describe physical attributes such as the size of an object or the height, weight, or dimensions of a person or thing. Additionally, it can be used metaphorically to describe concepts, events, or qualities that possess great significance, impact, or power.
Overall, while "are big" does not hold a specific definition on its own, it can be understood as an incomplete sentence where "are" acts as the verb indicating existence or identity, and "big" serves as an adjective describing something of notable size or importance.
