Sound by sound

Every sound in "flash".

1 syllable, 4 sounds. Explore each sound's mouth shape and how it's made.

f/f/

Lift your bottom lip to touch the very bottom of your top front teeth. Blow air through this contact point without voicing.

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.

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.

sh/ʃ/

Flare your lips and lift the mid-front tongue close to the roof of your mouth. Blow air through without voicing.

Questions

Questions people ask about this.

Is the American pronunciation of "flash" 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 "FLASH" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
