STRAIGHT, adjective [Latin , formed from the root of reach, stretch, right. It is customary to write straight for direct or right, and strait, for narrow, but this is a practice wholly arbitrary, both being the same word. Strait we use in the sense in which it is used in the south of Europe. Both sense proceed from stretching, straining.]
1. Right, in a mathematical sense; direct; passing from one point to another by the nearest course; not deviating or crooked; as a straight line; a straight course; a straight piece of timber.
2. Narrow; close; tight; as a straight garment. [See strait, as it is generally written.]
3. Upright; according with justice and rectitude; not deviating from truth or fairness.
