why are there so many different types of words
Words reflect ideas, or actions. There are a lot of choices for these. And many people see the same thing differently, so use different words to describe it.
I'm not sure, but I think you might be asking why there are so "many different types of words" for the same concept.
If this is so, they may reflect small variations in the concept or different origins for the words. The Sapir-Whorf hypothesis deals with some of this.

I also searched under "language variation" to get these sources:

This may be more information than — or not the information — you wanted, but I hope it helps a little more. If not, respond to this post with more specific questions. Thanks for asking.
There are many different types of words because language is complex and constantly evolving. Words are created to express new concepts, describe specific actions or objects, and convey different shades of meaning.
One reason for the variety of words is that different languages have different structures, sounds, and grammatical rules. Each language has its own unique set of words that have developed over time to fit the needs and culture of its speakers.
Within a single language, there can be multiple words or terms for the same concept. This is often influenced by factors such as regional variations, historical influences, and social groups. For example, in English, there are synonyms like "sad" and "unhappy" that both convey a similar meaning but have slightly different connotations.
Additionally, words can change and evolve over time. New words are constantly being coined to keep up with advancements in technology, science, and culture. For example, words like "selfie," "emoji," and "vlog" have entered our vocabulary in recent years.
In summary, the diversity of words is a result of language's flexibility and adaptability, reflective of the complexity of human thought and expression.
