1) This can be an alternative spelling of ‘dole’.
1518 I will ther noo daile be maide ... for me called penny dolle nor enny almesse delte, Flamborough. It also referred commonly to a share of land in the town fields, arable or pasture, but since it occurs in areas where ‘dales’ are also valleys it can cause confusion. Usually the context makes the meaning clear: 1610 for goeing very often over the great dale, Airton
1617half of one part of meadow lying in Green Karre … and half of another part in the Grasse-dales, Myton on Swale
1723 also the closes, inclosures, dales and parcels of arrable land, meadow and pasture ground, Aysgarth.
2) A regional word for valley, used commonly as a place-name element and often said to reflect Old Norse influence.
1558 To every howse in the dale the day of my buryall ijd, Westerdale. In some cases though an Old English connection seems more likely. 1572 the said daile called Bradfurthe-daile.
