形 (xíng): This character means “form,” “shape,” or “appearance.” It's the physical outline of something.
式 (shì): This character means “style,” “pattern,” or “ceremony.” It refers to a specific way of doing things, like a formula or a ritual.
主义 (zhǔyì): This is a very common suffix that means “-ism,” denoting a doctrine, ideology, or system of belief. You see it in words like `资本主义 (zīběnzhǔyì)` (capitalism).
When you combine them, `形 (form) + 式 (style) + 主义 (-ism)`, you get “form-style-ism.” This perfectly illustrates the concept: a system or mindset obsessed with the outward form and style of an action, while ignoring its internal substance and effectiveness.
