Vowel Sorting and Stress Shift
At a Nara junior high school, four students are sorting words from a pronunciation worksheet before the entrance exam. The worksheet has three vowel-sound columns: /e/ as in bed, /iː/ as in see, and /eɪ/ as in day. The words are great, bread, heat, break, said, paid, and read. Yui puts great and break in the /iː/ column because she says the letters ea usually sound like 'ee'. Haruto puts said in the /eɪ/ column because it looks like paid. Mei says read belongs in both /iː/ and /e/ columns, which the teacher says is possible only if the meaning changes. The teacher also writes two stress patterns on the board: Ooo for photograph and oOo for photography. She asks the group two questions and gives them five minutes to agree. The group may use only the worksheet and their own knowledge; no dictionary is allowed. One student wants to answer by saying 'these are exceptions, so memorize them', but the teacher will not accept that as an explanation.
1. Sort the seven words into the three vowel-sound columns, and explain which student's spelling-to-sound rule is the most misleading. Include how the two pronunciations of read affect the sort.
Read the worked answer
- Sort by sound, not by spelling.
- /e/: bread, said, read (past tense, meaning 'read a book yesterday').
- /iː/: heat, read (present tense, meaning 'read every day').
- /eɪ/: great, break, paid.
- Yui's rule ('ea usually sounds like ee') is the more misleading one because it fails on several common words: great and break are /eɪ/, and bread is /e/. The 'ee' value is common, but the exam item is testing whether you check the whole word and its meaning, not just the letters ea.
- Haruto's rule is also wrong but narrower: said is an exception to the 'ai = /eɪ/' pattern seen in paid. One exception is easier to remember than a whole unreliable rule.
- read is a special case because the spelling does not change; the meaning and tense do. The present form is /iː/ and the past form is /e/. That is why Mei can put it in two columns, but the answer must label which meaning goes where.
- A good exam explanation uses known rhyme sets (great/late, break/cake, said/bed) to justify the sound instead of saying only 'exception'.
2. The teacher asks: 'If photography is stressed oOo, where does the main stress fall, and what should you mark on an exam item that asks for the stressed syllable?' Explain the pattern using photograph and photography, and state one limit of the Ooo/oOo notation.
Read the worked answer
- In photography, the pattern oOo puts the main stress on the second syllable: pho-TOG-ra-phy. On an exam, mark the second syllable, not the first.
- The shift is not random: photograph has stress on the first syllable (PHO-to-graph), but the suffix -y in photography pulls the main stress to the syllable just before it. A related form, photographic, shifts the stress again to the third syllable.
- The safe reasoning is: identify the suffix and the syllable count first, then place the stress. Do not assume that a family of words keeps the same stress pattern.
- Limit of Ooo/oOo: it shows only the position of main stress, not vowel quality, secondary stress, or reduced vowels. It also does not show how fast or slowly a speaker says the word. So it is useful for marking the stressed syllable, but it cannot by itself tell you the full pronunciation.
