Answer:
The word "envious" means full of envy.
Explanation:
A suffix is a letter or group of letters added to the end of a word to change it into a new word by altering its meaning. The suffix -ous forms adjectives that have the general sense of possessing a quality, of being full of such quality. For instance: joy - joyous.
The suffix -ous and its variant -ious have often been used to anglicize Latin adjectives that have terminations which cannot be adapted to English. For instance: contiguous; atrocious.
Based on that knowledge, the adjective "envious" means "full of envy", "jealous".
