Here's how it works:
* Verb: "to slave" (meaning to work very hard, often in a forced or unpleasant way)
* Past participle: "slaved" (used in past tenses and perfect tenses, as well as in participial phrases)
For example:
* Past tense: They slaved away for hours to finish the project.
* Present perfect tense: They have slaved away for years to build this business.
* Participial phrase: Slaved by their debts, they couldn't enjoy their time off.
It's important to note that "slaved" can also be used as an adjective in some contexts, but this usage is less common and often carries a negative connotation. For example: "The slaved workers had no rights."
