Here's why:
* Stress in language refers to the emphasis or prominence given to syllables in a word.
* Primary stress is the strongest emphasis, often marked with a symbol like an apostrophe (').
* Secondary stress is a weaker emphasis, often marked with a smaller symbol like a comma (,) or a smaller apostrophe.
* There's no widely recognized concept of "tertiary stress" as a distinct level of emphasis.
Example of primary and secondary stress:
* "re'cord'ing" - Primary stress on the first syllable, secondary stress on the third syllable.
Important Note:
- The occurrence and placement of stress are language-specific. The examples above follow the typical stress patterns of English.
- Some languages have more complex stress systems.
If you have a specific example in mind, please provide it, and I can help you analyze the stress pattern.
