What does doty mean?
Doty is a chiefly American adjective used to describe wood that is partly decayed — soft, spongy, and no longer structurally sound. It belongs especially to the vocabulary of northern and New England speech, where it long served loggers, sawyers, carpenters, and timber buyers who needed a quick verdict on whether a stick of lumber was worth using. A doty plank might look acceptable on the outside yet crumble under a chisel, so the word carries a distinctly negative judgment about hidden rot. By natural extension it can be applied loosely to other things weakened by age, damp, or neglect. Though somewhat old-fashioned today, doty survives in rural speech and trade talk, and it remains useful precisely because it names a specific condition between fully sound and completely rotten. Writers reaching for a vivid, homespun way to describe compromised timber will find few words more exact.
adjective(Of wood or timber) partly decayed, soft and spongy from rot; not fully sound. It can also describe anything that has become weakened or deteriorated through age or damp.
- (Of wood) partly rotted, soft, and unsound.
- By extension: weakened or impaired through age, damp, or decay.
"The carpenter rejected the beam as doty and sent back to the yard for sound lumber."
"The old barn was full of doty planks that crumbled at the touch of an auger."
"He tapped each log with his axe to hear whether any had gone doty inside."
A single word American lumberjacks and carpenters have used for generations to condemn a rotten board: if it's doty, it's headed for the scrap pile.

Etymology of doty
The origin of doty is uncertain, though it appears to be native to American English, first recorded in the early nineteenth century in northern and New England usage. One plausible account links it to "dote," meaning to decay or decline, which itself descends from Middle English and shares roots with "dotage" — the notion of something failing through weakness of age. Whatever its precise ancestry, the word established itself firmly in the speech of lumbering regions, where it named the familiar problem of timber gone soft from rot.
How doty is actually used
Regional and somewhat old-fashioned in American English, heard most often in New England, the Upper Midwest, and among loggers, sawyers, and timber buyers. It is informal to neutral in register and carries a plainly negative connotation when applied to lumber.
