The word ‘from’ is a preposition. Prepositions are words that show the relationship between a noun (or pronoun) and other words in a sentence. They often indicate direction, place, time, or method.
For example, in the sentence ‘She traveled from New York to Los Angeles,’ the word ‘from’ shows the starting point of the journey. It connects the subject (She) with the location (New York).
Prepositions like ‘from’ are essential in English because they help clarify the relationships between different parts of a sentence. Without them, sentences can become confusing or lose their intended meaning.
