📐 模 = mold/pattern + 式 = form/style; together: a standard pattern
模 originally meant a wooden mold for casting; 式 means form or ceremony. Combined, 模式 names the template or mode something follows — a fixed pattern, formula, or operating mode.
式 — 工 (work) + 弋 (phonetic)
式 is a phono-semantic compound: 工 ('work, craft') gives the meaning of a tool, rule, or method, while 弋 supplies the sound. It originally referred to a standard pattern or model used in craftsmanship, then broadened to mean 'style, form, ceremony, or formula.'
