uh/ʌ/
Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.
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.
eh/ɛ/
Drop your jaw moderately. Touch the tongue tip behind the bottom front teeth and lift the mid-front part slightly toward the roof.
k/k/
Raise the back of your tongue to touch the soft palate (velum). Stop the air, then release.
y/j/
Lift the middle of your tongue toward the roof of your mouth, but stop just short of touching. /j/ is an approximant, not a stop. The tongue tip stays down, lightly resting near the back of your bottom front teeth. Voice runs through the whole gesture, and the tongue glides smoothly down into the next vowel. The lips stay neutral or pre-shape for the upcoming vowel (rounding early for OO in <em>youth</em>, for example).
uh/ʌ/
Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.
l/l/
SyllabicThe schwa before L disappears — L becomes the vowel of the syllable. Go straight from the previous consonant to a Dark L.
er/ər/
Relax your mouth and lift the tongue back and up. Keep the lips neutral.

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Stressing the wrong syllable.
Stress falls on the second syllable, not the others. Stretch LEH — keep everything else short and quick.
MUH·leh·KYUH·LER→muh·LEH·kyuh·ler
02
Pronouncing the first syllable too fully.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
MUH·LEH·kyuh·ler→muh·LEH·kyuh·ler
03
Pronouncing the "R" too clearly.
Americans use a relaxed retroflex R — the tongue curls back rather than rolling. The R is one continuous sound with the vowel before it, not two separate sounds.
… (no R)→… r (curl the tongue)
Questions
Questions people ask about this.
How is "molecular" stressed in American English?
Stress falls on the second syllable — say "LEH" with a longer, fuller vowel and keep every other syllable short and quick. The respell "muh-LEH-kyuh-ler" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why does the first syllable in "molecular" reduce to "uh"?
Unstressed syllables in American English collapse toward a schwa — a lazy, neutral "uh" sound. The full vowel is what textbooks teach, but in actual American speech every unstressed vowel reduces. The respell "muh-LEH-kyuh-ler" shows the reduced form so you can hear the casual rhythm directly.
How do I pronounce the R in "molecular"?
Americans use a relaxed retroflex R: the tongue curls back rather than rolling, and the R is one continuous sound with the vowel before it — not two separate sounds. Don't try to pronounce a separate vowel followed by a separate R. Treat them as a single shape.
Is the American pronunciation of "molecular" 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 "muh-LEH-kyuh-ler" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
