Question

sort the words by their vowel sounds. cop pot boat dome soap toss short o long o

Explanation:

To sort the words by vowel sounds:

• Short "o" sound: Words like "cop" (pronounced /kɒp/ or /kɑːp/ in some accents, but the short o sound is /ɒ/ or /ɑ/ in short vowel context), "pot" (/pɒt/ or /pɑːt/), "toss" (/tɒs/ or /tɑːs/) have the short o vowel sound.
• Long "o" sound: "boat" (/boʊt/), "dome" (/doʊm/), "soap" (/soʊp/) have the long o vowel sound (the long o is typically the sound of the letter name, like /oʊ/).

Answer:

Short o: cop, pot, toss
Long o: boat, dome, soap
