No entry in Lane's Arabic-English Lexicon for the root ق ص و. Lane (d. 1876) died before completing the lexicon, and its later volumes are thin or absent — this root falls in that gap. Its absence here means only that Lane has no article for it, not that it has no meaning.
The roots that most often share a verse with ق ص و. Window: the verse. Measure: the number of distinct verses in which both roots occur (of the 5 this root appears in). Ubiquitous roots are excluded so genuinely connected concepts surface — see the method.
