Final answer:
Prepositions, conjunctions, symbols, and articles are parts of speech in English with specific grammatical functions, unlike mathematical symbols which are arbitrary labels.
Step-by-step explanation:
Prepositions, conjunctions, all symbols, and articles are parts of speech which play crucial roles in the construction of sentences. Unlike mathematical symbols which are labels and lack intrinsic meaning, these parts of speech carry specific grammatical functions. For instance, prepositions indicate relationships between different elements within a sentence, conjunctions connect clauses and coordinate words, and articles define the noun’s degree of specificity.
Common subordinating conjunctions like 'although', 'since', and 'unless' introduce dependent clauses and cannot stand alone as complete sentences. Moreover, the reference of pronouns is an important aspect of maintaining clarity in writing, serving as substitutes for nouns or noun phrases. In the context of parts of speech, components like prepositions, conjunctions, and articles are integral to the clear and coherent construction of sentences in the English language.
