1 syllable, 3 sounds. Explore each sound's mouth shape and how it's made.

l/l/

Place the tip of your tongue against the alveolar ridge just behind your top front teeth, the same contact point as /t/, /d/, and /n/. The difference is what happens to the air: for /l/, you let it flow continuously around the <em>sides</em> of the tongue (that's why /l/ is called a lateral). Turn your voice on the whole time. Lips stay relaxed, no rounding or flaring. For the Dark L variant at the end of a syllable, also pull the back of the tongue up and back toward the soft palate.

Mouth position for /l/ as in LET
a/æ/

Drop the jaw noticeably. Keep the body of the tongue low and forward, and don't let the back of the tongue raise toward the soft palate. Pull the lip corners back slightly, almost a starting smile.

Mouth position for CAT Vowel

Press your lips together, add vocal cord vibration, then release.

Questions

Questions people ask about this.

Is the American pronunciation of "lab" different from British English?
American English uses different vowel shapes, a relaxed retroflex R, and connected-speech tricks like flap-T and glottal-stop T that British Received Pronunciation generally avoids. The respell "LAB" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.

Stop reading about "lab". Start saying it.
