mates

Mates is the plural of mate and is used in English to refer to friends or companions. The word also appears as a verb in biological contexts, meaning to pair for reproduction, and forms part of compound terms such as housemate, classmate, or workmate. As a verb, mate can describe the act of pairing in nature or, more informally, the process of joining or pairing in human contexts.

In everyday language, mate is commonly used as a form of address. In Australia and New Zealand, it is a widespread term of friendly address and can be directed at strangers or acquaintances, often with a warm or informal tone. In the United Kingdom and Ireland, mate is also used, though its frequency and connotations can vary by region and social setting. Beyond address, the word appears in many compound forms that denote shared living or school contexts, such as roommate or classmate, and in professional settings as workmate.

The concept of mateship—often associated with Australia—embodies themes of loyalty, mutual aid, egalitarianism, and camaraderie across social groups. While the core idea exists in various cultures, the specific ethos and celebration of mateship are particularly noted in Australian cultural discourse.

Etymologically, mate originates from older English and related Germanic terms and has developed across English-speaking regions. Its usage remains highly context-dependent, ranging from casual address to formal or technical senses in biology and social life.
