Final answer:
The words 'burned' and 'stressed' in the examples given act as participles, which are verb forms used as adjectives to modify nouns.
Step-by-step explanation:
In the examples given, 'burned' modifies 'toast' and 'stressed' modifies 'mom', these are both examples of participles acting as adjectives. A participle is a verb form that can be used as an adjective to modify nouns or pronouns. In the sentences provided, burned is a past participle modifying the noun toast, and stressed is also a past participle modifying the noun mom. Participles can be positioned before or after the nouns they modify and can be part of a larger participial phrase which might include its own modifiers and complements. They add descriptive detail to a sentence, just like adjectives do.
It is important to identify the various parts of speech in a sentence including nouns, adjectives, verbs, and adverbs, as well as the phrases that function as these parts of speech such as prepositional phrases, appositives, and participle phrases. This helps in understanding the sentence structure and the relationships between different elements of a sentence.
