📋 格 (frame/grid) + 式 (style/pattern) = format
格 originally meant a wooden frame or grid (think of grid squares on graph paper), and 式 means style or pattern. Together they name the structured style something follows — a format or template.
格 — wood 木 + 各 (each, phonetic)
格 is a semantic-phonetic compound: 木 (wood) gives the meaning, originally referring to a wooden frame, lattice, or crossbar, while 各 supplies the sound. From 'frame/grid' the meaning extended to 'pattern, standard, style' and the modern senses of 'square (in a grid)' and 'character/disposition'.
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.'
