Mecha, the term for giant robots in Japanese popular culture, has spawned a variety of synonyms over the years. Some of these terms include mechanical, mechy, mekka, mek, and mekano. These words are often used interchangeably, and each has its own connotations. Mechanical is the most general, describing anything relating to machines, while mechy and mekka are more specific to giant robots. Mek and mekano are less commonly used, but they convey a certain sense of coolness. Mecha enthusiasts often use these words to differentiate between different types of robots, or to simply have a wider vocabulary when discussing their favorite anime.
