Structural Breakdown
The word “unstable” is formed by adding the prefix “un-” to the adjective “stable.” The prefix “un-” generally negates the meaning of the word it precedes. Understanding prefixes and suffixes is crucial for expanding vocabulary and comprehending the meaning of unfamiliar words.
Here’s a breakdown:
- un-: Prefix meaning “not”
- stable: Adjective meaning “firmly established; not likely to change or fail”

The form of antonyms for “unstable” will vary depending on the specific word. Some antonyms are formed by adding prefixes like “im-” or “in-” to words, while others are completely different words with opposite meanings. For example:
