The American O sounds can be difficult. There are 3 distinct sounds, the short O as in “hot,” the long O as in “boat,” and the reduced O. The phonetic name is the schwa sound, as in “above” (say “abuv”). The basic rules are these:
- Use short O for simple spellings in words or word parts
- Use long O with complex spellings, i.e., a silent vowel near the O
- Use the reduced O (the “u” as in “up”) sometimes when O is not stressed
- Most exceptions to the above rules will be found in very common words
Overall, the best thing to do is realize that O has three sounds. Listen carefully to American English speakers and take the time to look up the pronunciation of words.
