The word "shall" is a modal verb used primarily to indicate future actions or intentions. It is often employed 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 A shall deliver the goods by date." In modern English, "shall" is less common in everyday conversation, where "will" is often preferred. However, it still appears in certain phrases and is sometimes used to convey a sense of determination or promise, as in "I shall complete the project."
