Final answer:
Word parts like phonemes and morphemes work together to form words and express meanings. Understanding semantics and syntax is crucial to grasp the use of different parts of speech in sentence construction.
Step-by-step explanation:
Word parts work together to form the building blocks of language, allowing us to create a vast array of words and expressions. In English, the different types of word parts include phonemes, which are basic sound units, and morphemes, the smallest units that carry meaning. An understanding of semantics and syntax, which are crucial components of grammar, enables us to derive meaning from words (semantics) and organize these words into sentences (syntax). Parts of speech, such as nouns, adjectives, verbs, and adverbs, are essential in constructing phrases and sentences. These parts of speech serve different functions and can change in form, demonstrating the importance of both form and function in language comprehension and usage.
