Final answer:
The first words spoken in any language are typically nouns. Children start with concrete nouns and later integrate other parts of speech. Words borrowed from other languages are usually unique objects or concepts, not basic words like family member terms or pronouns.
Step-by-step explanation:
The first words spoken in any language are typically nouns. This category of words represents people, places, things, and ideas, and are usually the most essential elements for naming and identifying objects in our environment, which is critical during the early stages of language development. The process of language development underscores how children are predisposed to acquire language, often starting with concrete nouns that label their immediate reality. As language acquisition progresses, other parts of speech such as pronouns, verbs, adjectives, and adverbs become integrated, allowing for the creation of more complex expressions and thoughts.
Regarding the vocabulary we borrow from other languages, words for unique or novel objects, ideas, technologies, or cultural concepts are the most common borrowings, rather than words for family members or pronouns, which are deeply embedded in the structure of a language and are less likely to be replaced.
