Perhaps you meant one of these:
* Spoonerism: This is a common type of speech error where the initial sounds of two words are switched. For example, "a blushing crow" instead of "a crushing blow."
* Sonar: This is a system that uses sound waves to detect and locate objects underwater.
* Spondee: This is a poetic meter with two stressed syllables.
* Sporadic: This means occurring at irregular intervals or in scattered locations.
Could you please clarify what you meant by "sponarism"? I'd be happy to help you find the correct term or definition.
