132 11 "heros"/"heroes" - Of the two spellings of the plural of "hero," "heroes" is more common. The first printing used "heros," since it follows the plurals rules students have learned. The second printing substitutes the more common spelling. Students have learned the phonongram OE, but the word is irregular in how the plural is formed. If you choose to use "heroes," be sure to support students by cuing the OE phonogram. (Several other words ending in O form irregular plurals the same way: tomatoes, potatoes)

This rule limits when y can say /ē/; however, it does not limit what y can say in that position. Y can say another sound at the end of the word: /ī/ as in reply.)
