Final answer:
To find the letters that spell the sound [j] in the word 'judge', both the 'j' at the beginning and the 'dg' before the silent final 'e' are underlined, representing the sound [j].
Step-by-step explanation:
To review the spellings of the sound [j] in various words, we examine the letters used to constitute this sound in English. This sound can be represented by multiple spellings, including , , and , and sometimes a single word may contain the sound spelled in two different ways.
For example, you can hear the sound [j] at the beginning and end of the word 'judge'. To identify the spelling of this sound, we should underline the letters that spell [j], as per the student's exercise. Therefore, in 'judge', the letters that would be underlined are 'j' and 'dg', because the silent final is not considered part of the spelling for the sound [j].
