Another difference between tonal languages is whether the tones apply independently to each syllable or to the word as a whole. In Cantonese , Thai , and to some extent the Kru languages , each syllable may have a tone, whereas in Shanghainese , [ citation needed ] the Scandinavian languages , and many Bantu languages , the contour of each tone operates at the word level. That is, a trisyllabic word in a three-tone syllable-tone language has many more tonal possibilities (3 × 3 × 3 = 27) than a monosyllabic word (3), but there is no such difference in a word-tone language. For example, Shanghainese has two contrastive tones no matter how many syllables are in a word. [ citation needed ] Many languages described as having pitch accent are word-tone languages.
In an ideal world, people would call to mind the essential guidelines every time they wrote something until these became second nature. In our less-than-ideal world, it can be difficult to even get someone to sit down and read something once. Therefore, it’s essential that the guide is both easy-to-digest and memorable. You may want to include a one-page summary of the guide’s most important points right at the beginning. These would focus on the personality behind the tone of voice, rather than the specifics of grammar (which can be more easily edited at a later stage of the editorial process).
