Question

sort the words by their vowel sounds.
loss note float won rope
short o
long o

Explanation:

To sort the words by vowel sounds:

• Short "o" sound: "loss" (pronounced /lɒs/ or /lɔːs/ in some accents, short o), "won" (pronounced /wʌn/, but the vowel here is a short vowel sound related to o - like in some dialects or when considering vowel classification for this task, "won" has a short vowel sound that can be grouped here).
• Long "o" sound: "note" (pronounced /nəʊt/ or /noʊt/, long o), "float" (pronounced /fləʊt/ or /floʊt/, long o), "rope" (pronounced /rəʊp/ or /roʊp/, long o).

Answer:

Short o: loss, won
Long o: note, float, rope
