"In common use almost every word has many shades of meaning, and therefore needs to be interpreted by the context"

This quote by Alfred Marshall speaks with the intricacy of language and how words can have numerous significances. He is recommending that words can have different analyses depending on the context in which they are used. This is because words can have different connotations and subtleties depending upon the circumstance. For example, the word "love" can suggest various things depending on the context. It can indicate a strong emotion between two individuals, or it can suggest a fondness for a particular activity or hobby. Therefore, it is essential to think about the context when interpreting words. Marshall is highlighting the significance of understanding the context in order to precisely analyze the significance of words. He is recommending that words can have numerous meanings and that it is essential to consider the context in order to comprehend the designated significance.
