RUN OUT means "to exhaust a supply" or "to have none left" — an essential phrasal verb for everyday situations.
Basic Pronunciation
Stress Pattern
Stress falls on OUT:
- run = less stressed
- OUT = main stress (louder, longer)
Say: "run OUT" not "RUN out"
Connected Speech
The /n/ at the end of "run" links smoothly to the diphthong /aʊ/ in "out":
- Written: run out
- Sounds like: "ru-NOUT" /rʌˈnaʊt/
The /n/ "jumps" to connect with the vowel sound.
With Prepositions
The /ʌ/ Vowel in "Run"
"Run" has the /ʌ/ vowel — a central, unrounded vowel:
How to make /ʌ/:
- Mouth slightly open
- Tongue in the center, relaxed
- Lips NOT rounded
- Similar to "uh" in unstressed syllables
The /aʊ/ Diphthong in "Out"
"Out" contains the diphthong /aʊ/:
- Start with mouth wide open /a/
- Glide to /ʊ/ with rounded lips
Different Uses
1. Exhaust a supply
2. Expire

Inseparable Verb
RUN OUT is inseparable:
- ✅ "We ran out of gas."
- ❌ "We ran gas out of."
The American /r/ Sound
The /r/ in "run" is crucial. Don't roll it like Spanish:
- Curl your tongue tip back
- Don't touch anything
- Lips slightly rounded
Common Mistakes for Spanish Speakers
1. Rolling the /r/
Don't roll the R in "run." Curl your tongue back instead.
2. The /ʌ/ vowel
The vowel in "run" is NOT the Spanish "a" or "o." It's a central, unrounded sound.
3. The /aʊ/ diphthong
Make sure to glide from /a/ to /ʊ/ in "out."
