salt · fault
Same long /ɔː/ vowel and /lt/ ending — only the first sound differs: /s/ vs /f/.
Both words have the exact same vowel /ɔː/ and ending /lt/. The only difference is the first sound — salt starts with /s/ (tongue near the ridge, a hiss), fault starts with /f/ (upper teeth on lower lip, a rush of air).
noun / verb — (1) the white mineral used to season food — 'table salt' · 'sea salt' · 'salt shaker' · 'season with salt'; (2) verb: to add salt — 'salt the pasta water'; (3) idiom: 'take it with a pinch of salt' (treat sceptically) · 'salt of the earth' (a good, reliable person)
mouth shape
unvoiced /s/ — SAWLT — tongue tip near the ridge behind your upper teeth, air flows over it with a hiss — then the long /ɔː/: lips round and hold steady — ends with /lt/ cluster
salt
/sɔːlt/
vowel length
noun / verb — two distinct meanings: (1) blame or responsibility — 'it’s my fault' · 'at fault' · 'find fault with' · 'no-fault'; (2) a fracture in rock where one side has shifted — 'San Andreas Fault' · 'fault line' · 'geological fault' · verb: 'you can’t fault her work'
mouth shape
unvoiced /f/ — FAWLT — upper teeth rest on lower lip, air flows through — then the same long /ɔː/ as salt — ends with /lt/ cluster — the L is sometimes lightly pronounced before the T
fault
/fɔːlt/
vowel length
Consonant spotlight — initial /s/ vs /f/
salt
/sɔːlt/
/s/ — tongue near ridge, air hisses
like: sun · sea · sing · sit
fault
/fɔːlt/
/f/ — teeth on lip, air rushes through
like: fun · far · feel · find
/s/ and /f/ are both unvoiced fricatives — neither one uses vocal cord vibration. The difference is where the air escapes: /s/ sends air over your tongue tip (alveolar); /f/ sends air between your upper teeth and lower lip (labiodental). You can see the difference in a mirror.

fault — two very different meanings, one word
Meaning 1 — Blame
Responsibility for something wrong
“It’s not my fault the train was late.” · “She was at fault.” · “You can’t fault the logic.”
Meaning 2 — Geology
A fracture in the earth’s crust
A crack where one side has shifted relative to the other — “the San Andreas Fault” · “a fault line.”
Key difference
Same vowel /ɔː/, same ending /lt/ — only the first consonant changes. salt /s/: tongue near the alveolar ridge, air escapes over the tip — a hiss. fault /f/: upper teeth rest on the lower lip, air escapes through — a rush.
