So, late O.E. lāh = low from Scand. lār became law- in oblique cases and gave rise to Mod.Sc. law in lawland(s), shortened into lallan(s). Lāh gave rise to Mod.Sc. laich but we find in O.Sc. forms like lawche where the vowel of the oblique cases has been transferred to the nominative form. See § 30. § 35. Words with ō in O.E. O.E. ō. — m.bk.t.r., Middle Sc. o' oi, u, u + cons. +e, ui. ō at an early period began to shift forward in the mouth until it became a front vowel like the Fr. eu [ø] = m.fr.t.r. Generally when the vowel was in final position, or occurred before [r, z, ð, v,] it remained [ø], but before other consonants it was raised to or towards the high front position, and became lax, resembling the Ger. ü in hütte. It is a fact that when ui (O.E., Rom., or Scand. in origin) is unrounded in some Mod. dialects — e.g. em.Sc.,wm.Sc. — two distinct vowels are the result — e.g. guid becomes gid, brute becomes brit, shune becomes shin, use (n.) becomes yis, but ruise (= praise) becomes raise [re:z], muir becomes mair [me:r], use (v.) becomes yaise [je:z], shoe becomes shae [&sh.e:]. In the dialects of Ags. and the Mearns and of Ork. and Sh. the ui vowel has the same value in all words where it occurs — i.e. m.fr.t.r. = [ø]. When it is unrounded by younger speakers in Ags. and the Mearns the result is the same for a]] words — viz. [e1 or e]. Sometimes in other dialects there is a mixing of the two classes, generally by the working of analogy. See § 30.
