The word "small" is pronounced differently in American and British English:

• In American English, it is pronounced as /smɑːl/, with the phonetic spelling "smAHl."
• In British English, it is pronounced as /smɔːl/, with the phonetic spelling "smAWl."

Both pronunciations start with the "s" sound as in "say," followed by the "m" sound as in "moon," and end with the "l" sound as in "look." The main difference lies in the vowel sound in the middle: American English uses an "ah" sound as in "father," while British English uses an "aw" sound as in "horse".
