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'.
