Shall
The word "shall" is a modal verb used primarily to indicate future actions or intentions. It is often used in formal contexts, such as legal documents or official statements, to express obligations or requirements. For example, in a contract, one might say, "The party shall deliver the goods by the specified date."
In everyday language, "shall" is less common and is often replaced by "will." However, it can still be used to make suggestions or seek agreement, as in "Shall we go to the park?" This usage emphasizes a polite invitation or proposal, making it suitable for social interactions.
