All entries are lower case except names, days and months etc. As in Standard English.
Compound words may also be found by entering one or other of their constituent words.
Try using uninflected words i.e. make the word singular by dropping final <(e)s>, adjective and adverbial <(l)ie> or <(l)y>, the gerund or present participle <-in> and <-en>, <-an> or <-een> (ing), the past tenses <(e)d> and <it> or <et>, the comparative and superlative <er> and <est>, etc.
You may need to add the final <e> when removing inflections.
Shorten the phrase or use individual words.
Try avoiding apostrophes representing the "missing" <d> in final <ld> and <nd>. Similarly instead of <a'> try <au> or <aw> and instead of <in'> try <in>. Apostrophies may also represent a "missing" <e> in the past tense <ed> e.g. <'d>.
Diacritics are not normally used in Scots, however, some insist on experimenting with them.
With letters such as <ä>, <é>, <ï>, <ò> and <ü> simply use the letters without diacritics. For <ö>, <ø> and <ü> substitute <ui>.
Use final <ae> or <a> instead of <ow>.
Use <wh> instead of <quh> or <f>.
Use <ck> instead of <k> or <kk>.
Use final <er> instead of <ir> or <ur>.
Use <it> for the past tense instead of <et> or <eet>.
Use final <le> instead of <il> or <ul> and for the past tense <elt> instead of <ilt>, <ult> or <led>.
Use the gerund or present participle <in> instead of <ing>, <an>, <en> or <een>.
Varying use of <ae>, <ai> and <a(consonant)e>.
Varying use of <aa>, <au> and <aw>.
Varying use of <ea>, <ee>, <ei>, <ie> and <e(consonant)e>.
Varying use of <oo> and <ou>.
Varying use of <oo>, <u(consonant)e>, <i>, <ai> and <ee> for <ui> i.e. use <ui> instead of <oo> or <u(consonant)e> (<eu> before <k> and <ch>).
Varying use of <ow> and <ou>. Note final <owe>.
Varying use of <se>, <ss> and <z(e)>.
Varying use of final <y> and <ie> for adverbs and adjectives. Diminutives usually use <ie> rather than <(e)y>.
