Here's why:
* General dictionaries (like Merriam-Webster or Oxford English Dictionary) are primarily concerned with the current meaning and usage of words. They might offer brief etymological information (origin of the word) but won't go into extensive historical detail.
* Etymological dictionaries are specifically designed to trace the history of words, providing in-depth information about their origins, changes in meaning, and relationships to other languages.
* Historical dictionaries focus on the language of a specific period in time, offering insights into the vocabulary, grammar, and usage of that era.
So, while some dictionaries do provide information on the history of language, it's not a standard feature in all dictionaries. You'll need to look for specialized dictionaries like etymological or historical dictionaries if you're interested in this topic.
