-ous says US: famous, nervous, delicious
-ous se dit « eus » : famous, nervous, delicious

What French speakers do
You use the French -eux sound, stressed at the end: fa-MEU, ner-VEU, dé-li-SYEU.
The American rule
-ous = a weak US (/əs/), with a clear S at the end. The stress goes earlier: FAY-mus, NUR-vus.
French adjectives in -eux (fameux, nerveux, délicieux, dangereux) have English twins in -ous. The English ending is a tiny, unstressed -us, and the S is always pronounced.
Watch the vowels in front of it too: famous starts with the gliding AY (FAY-mus), and -cious / -tious is -shus: delicious = dih-LISH-us.
