Which suffix is commonly associated with adjectives like "destructive"?

The suffix that is commonly associated with adjectives like "destructive" is indeed -ive. This suffix is often used to form adjectives that express a tendency or capability, suggesting that something has the quality of the root word. In the case of "destructive," it conveys the ability to cause destruction.

The other suffixes serve different functions: -ous is typically used for adjectives that denote a fullness or abundance of a quality, such as "joyous" or "famous." -ment is a suffix that creates nouns indicating the state or result of an action, like "enjoyment" or "development." Similarly, -er usually forms nouns indicating a person or thing that performs an action, such as "teacher" or "runner." Thus, these suffixes are not aligned with forming adjectives in the same way that -ive is.
