A tree's diary, written in rings and read in furniture stores.

means The natural pattern of lines and textures in wood, formed by the tree's growth layers, fibers, and rays.

from A plain compound: 'wood' from Old English 'wudu,' and 'grain' from Latin 'granum' (seed/kernel), which drifted over centuries from meaning a particle or texture to describing the fibrous streaks and patterns running through wood and other materials — the same 'grain' you find in 'grain of sand' or 'against the grain.'
