A blog about rook script, an alternative writing system for English

English is a stressed language. When speaking English, some syllables are held for longer, spoken louder, and voiced at a higher pitch than other syllables. That much we can say for sure.
When saying a sentence out loud, it can be difficult to explain which syllables should be stressed. To break the problem down a little bit, I differentiate between word stress and sentence stress. Every syllable of every word has intrinsic stress properties—it can have primary stress, it can be unstressed, etc. This is word stress, and it’s the focus of this page (and of rook script generally). Word stress helps determine sentence stress, but sentence stress also accounts for other factors, such as emphasis and maintaining a consistent rhythm. Because sentence stress can vary so much, spelling based on it would be unnecessarily difficult. I also don’t understand it very well and can’t explain how it works.
Rook script doesn’t even aim to capture all aspects of word-level stress1. Instead, it assigns to each syllable one of three levels, relative to surrounding syllables: primary stress, secondary stress, or no stress. The word “loquacious|lou·kwei·shis” has all three types: secondary·primary·none. Defining stress only up to adjacent syllables is an unusual convention. For example, in the word “paradigm|peir·ə·daim”, it’s fair to say the first syllable has more stress than the third syllable, so most dictionaries (see Merriam-Webster) will notate them as having different levels of stress.
However, in rook script, secondary stress always refers to a syllable that has some stress, but less stress than a neighboring syllable. Any syllable that has stress, and more stress than (both) its adjacent syllable(s), is said to have primary stress. According to rook script, the stress pattern of “paradigm” is primary·none·primary.
The official stress pattern of every word is given in the pronunciation columns of the rook script dictionary. In the dictionary, primary stress is indicated with an acute accent ´, secondary stress with a grave accent `, and unstressed syllables have no accent.
Stress interacts with spelling in two ways: limiting the vowels that can appear in unstressed syllables, and setting syllable boundaries. There are also limitations on which stress patterns actually appear within words in English.
Unstressed syllables are very limited. Here is a complete list of vowels that can appear in an unstressed syllable:
Some sources say ou can appear in unstressed syllables (Merriam-Webster is comically ambivalent), but in rook script ou always has some stress. I don’t know of any cases where this distinction would affect spelling.
Note that the letters ə and i can both appear in syllables with stress, but when they do they are not representing the weak vowel.
See the page on syllable boundaries for more context and other factors considered in placing syllable boundaries.
Stress is one of the factors in deciding where to place syllable boundaries between vowels. Generally, stressed syllables (whether primary or secondary) take as many consonants as possible, while unstressed syllables take as few as possible. For instance, the word “partial|paarsh·əl” has stress pattern primary·none, and so the sh is assigned to the first syllable rather than the second.
Between stressed syllables, morphological factors are often more important to the syllable boundary than the shape of the stress pattern. But sometimes, a syllable boundary can indicate that a syllable’s stress is only secondary. For example, in the word “survey (noun)|sərv·ei”, the vowel ei implies there must be some stress on the second syllable. But since the v is assigned to the first syllable, there must be more stress on the first syllable; indeed, the stress pattern is primary·secondary. This contrasts with “survey (verb)|sər·vei”, which has stress pattern none·primary.
There are also cases where the stress pattern does not affect spelling at all, often due to morphology. For example the related words “produce (noun)|prou·duus” and “produce (verb)|prou·duus” are spelled exactly the same, despite having different stress patterns: the noun is primary·secondary and the verb is none·primary. Note the verb is usually pronounced “prə·duus”, in contrast with the official spelling. In both cases the spelling aims to preserve the prefix “pro-|prou·”, which is very common and can help in understanding the meaning of a word when reading it.
It’s not necessary to know the exact stress pattern of a word to spell it correctly. I believe with some practice it becomes easy to intuit the way stress affects syllable boundaries. And I can attest that using syllable boundaries as hints to stress patterns makes reading faster.
Not all stress patterns are possible. For every pair of adjacent stressed syllables in English, one has greater stress than the other. This means in particular that there are never two primary-stress syllables in a row, since in any pair at least one will have secondary stress.
More surprisingly, it is very rare that a word will have two secondary-stress syllables in a row. I am aware of two examples, “antibiotic|an·tai·bai·aat·ik” (primary·secondary·secondary·primary·none) and “biotechnology|bai·ou·tek·naal·ə·jii” (primary·secondary·secondary·primary·none·none). Both are quite long words with multisyllabic prefixes. In principle, if a word has a sequence of stressed syllables either decreasing or increasing in stress level, there is no limit to the number of consecutive syllables with secondary stress. However, I do not believe any English words have more than two syllables with secondary stress in a row. To my knowledge, there are also no words with more than four stressed syllables in a row.
On the other hand, words tend not to go on too long without stress. As far as I know, there are never more than three unstressed syllables in a row. And most of the time there are three unstressed syllables in a row, it’s because the word ends in an unstressed suffix, as in “personally|pərs·ən·əl·ii”, which has pattern primary·none·none·none.
If you want to know how to pronounce a word, you will probably want to know which syllables of the word are most stressed compared to all other syllables in the word. This is what most dictionaries attempt to capture with their diacritics, and they use the same words, primary and secondary stress. ↩
