show the vowel was short and a heavier line to show the vowel was long: ᑲ ka, ᑲ kâ; however, in the 1841 version, a light line indicated minuscules ("lowercase") and a heavier line indicated majuscules ("uppercase"): ᑲ ka, ᑲ KA or Ka; additionally in the 1841 version, an unbroken letterform indicated a short vowel, but for a long vowel, Evans notched the face of the type sorts, such that in print the letterform was broken. A handwritten variant using an overdot to indicate a long vowel is now used in printing as well: ᑕ ta, ᑖ tâ. One consonant, w, had no letterform of its own but was indicated by a diacritic on another syllable; this is because it could combine with any of the consonants, as in ᑿ kwa, as well as existing on its own, as in ᐘ wa. There were distinct letters for the nine consonants -p, -t, -c, -k, -m, -n, -s, -y, and w when they occurred at the end of a syllable. In addition, four "final" consonants had no syllabic forms: -h, -l, -r, and the sequence -hk. These were originally written midline, but are now superscripted. (The glyph for -hk represents the most common final sequence of the language, being a common grammatical ending in Cree, and was used for common -nk in Ojibwe.) The consonants -l and -r were marginal, only found in borrowings, baby talk, and the like. These, and -h, could occur before vowels, but were written with the final shape regardless. (-l and -r are now written the size of full letters when they occur before vowels, as the finals were originally, or in some syllabics scripts have been replaced with full rotating syllabic forms; -h only occurs before a vowel in joined morphemes, in couple grammatical words, or in pedagogical materials to indicate the consonant value following it is fortis.) Vowel transformations The vowels fall into two sets, the back vowels -a and -u, and the front vowels -e and -i. Each set consists of a lower vowel, -a or -e, and a higher vowel, -u or -i. In all cases, back-vowel syllables are related through left-right reflection: that is, they are mirror images of each other. How they relate to front-vowel syllables depends on the graphic form of the consonants. These follow two patterns. Symmetrical, vowel, p-, t-, sp-, are rotated 90 degrees (a quarter turn)
