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.
uh/ʌ/
Relax your lips, jaw, and tongue completely. Drop your jaw slightly and keep the tongue neutral.
k/k/
Raise the back of your tongue to touch the soft palate (velum). Stop the air, then release.

Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Releasing the final consonant with a puff of air.
In "fluctuations", the "k" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.
fluctuations→FLUHK·choo·AY·shuhnz
02
Inserting a vowel before the syllabic consonant.
In "fluctuations", the short unstressed vowel before "n" disappears — the schwa is absorbed and the "n" becomes the syllable nucleus on its own. Schwa is absorbed — consonant becomes the syllable nucleus.
fluctuations→FLUHK·choo·AY·shuhnz
03
Stressing the wrong syllable.
Stress falls on the third syllable, not the others. Stretch AY — keep everything else short and quick.
FLUHK·CHOO·ay·SHUHNZ→FLUHK·choo·AY·shuhnz
04
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.

Questions
Questions people ask about this.
How is "fluctuations" stressed in American English?
Stress falls on the third syllable — say "AY" with a longer, fuller vowel and keep every other syllable short and quick. The respell "fluhk-choo-AY-shuhnz" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Why does the first syllable in "fluctuations" 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 "fluhk-choo-AY-shuhnz" shows the reduced form so you can hear the casual rhythm directly.
Is the American pronunciation of "fluctuations" 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 "fluhk-choo-AY-shuhnz" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
