SOOM, _vb._ to swim. Not Dan. _sömme_, but loss of _w_ before _oo_, cp. the two Norse forms _svömma_ and _symma_. Cp. _soote_, the last word in the first line of the Prologue to Chaucer's Canterbury Tales.
TEEM, _vb._ to empty. It is not necessary to derive this from Norse _tömme_, "to empty." There is an O.E. _tōm_ from which the Sco. adj. _toom_ probably comes. _Toom_ is also a verb in Sco. _Teem_ is simply this same word by characteristic Sco. change of _o_ to _e_. (See §17.) This also explains the length of the vowel.
TRAK, _vb._ to pull, not necessarily Norse _trekka_, cp. the L.G. _trekken_.
WID, _sb._ wood. Not O.N. _viðr_ nor Dan. _ved_. The vowel is against it in both cases. But just as above _toom_ becomes _teem_, so _wood_ > _wid_, cp. Sco. _guid_, "good," _pit_, "put," etc. (See §17.) Hence also the shortness of the vowel in _wid_.
WERE, _sb._ spring, cp. Latin _ver_. _Var_, _vaar_ in Scand. does not account for the _e_ in the Sco. word.
YIRD, _sb._ earth. Not from Dan. _jord_. See next word.
YIRTH, _sb._ earth, an inorganic _y_ (see §18). Not from O.N. _jörð_. For _d_ in _yird_ see §19.
I have adopted the following tests of form, meaning and distribution in determining the Scand. source of loanwords:
1. The diphthong _ou_, _ow_ corresponding to O.N. _ou_, O.E. _ea_.
2. _Ai_, _ay_ corresponding to O.N. _æi_, O.E. _ā_ as far as such words can be determined from modern dialects according to §20.
3. The spirant _th_ corresponding to O.N. _ð_, and O.E. _d_.
4. Consonantal assimilation of _nk_ to _kk_, _mb_ to _bb_, _mp_ to _pp_, _ðl_ to _ll_, _zd_ and _rd_ to _dd_, corresponding to similar assimilation in Scand.
5. Other consonantal and inflexional forms that are Scand., as opposed to O. Nhb. _d_ for Scand. _d_, O.E. _ð_ excluded, see §§19 and 23.
6. A word that is used in a sense distinctively Scand., as opposed to Eng. or L.G., is to be regarded as a loanword.
7. The distribution of a word in South England diall., or in O.F., O.S. or M.L.G., indicates that the word is not a Scand. loanword.
8. On the other hand, if a word occurs exclusively in Scand. settlements in England and Scotland, it is to be regarded as due to Scand. influence in Scotch in spite of L.G. parallels.
