Schwi

Similarly the syllable "day" in "Sunday" is to be printed smaller than the rest of the type and in the higher position to show, first that the vowel is unstressed and second that the sounds needs to be "schwi,"

Accent Hint No. 1 -- if the first syllable contains a one-syllable prefix, the vowel in that syllable is unaccented and thus is probably a schwa /ə/ or schwi /i/.

Should the schwa [ago] and schwi [very] be represented with a unique phonogram?
