Pronouncing /æ/ vs. /ɑː/ (cat vs. father)

Understanding /æ/ and /ɑː/

The vowel sounds /æ/ and /ɑː/ are often confused by English learners. They differ in tongue position, mouth opening, and length.

• /æ/ – A short, front vowel, as in cat, man, sad.

• /ɑː/ – A long, open back vowel, as in father, car, start.

The cat ran past the parked car.

Key Differences

1. Tongue Position – /æ/ is pronounced with the tongue lower and more forward, while /ɑː/ is produced with the tongue lower and further back.

2. Mouth Shape – /æ/ requires a wider mouth opening, while /ɑː/ has a more relaxed, open shape.

3. Length – /æ/ is short, while /ɑː/ is long and held for a longer duration.

4. Common Spelling Patterns

   • /æ/ – Usually spelled with “a” (e.g., cat, hat, apple).

   • /ɑː/ – Often spelled with “a” or “ar” (e.g., father, car, star).

Common Minimal Pairs

• cat /kæt/ vs. cart /kɑːt/

• man /mæn/ vs. mar /mɑːr/

• hat /hæt/ vs. heart /hɑːt/

• bad /bæd/ vs. bard /bɑːd/

Example Sentence

• "The cat ran past the parked car."

  • "Cat" and "ran" contain the short /æ/ sound.

  • "Past," "parked," and "car" have the long /ɑː/ sound.

How to Practice

1. Listen and Repeat – Find recordings of native speakers pronouncing /æ/ and /ɑː/ words and repeat after them.

2. Minimal Pair Exercises – Say pairs of words aloud to feel and hear the contrast.

3. Use a Mirror – Observe how your mouth shape changes when pronouncing each sound.

4. Record Yourself – Compare your pronunciation with that of a native speaker.
