roscid
Containing or consisting of dew; dewy.
archaic
The differences of earths and the trial of them, are worthy to be diligently inquired […] It is thought by some, that the ends of low rainbows fall more upon one kind of earth than upon another; as it may well be; for that that earth is most roscid: and therefore it is commended for a sign of good earth.
Where it comes from
Borrowed from Latin roscidus, from ros, roris (“dew”).
