Use of Shall

"Shall" is used to indicate future action. It is most commonly used in sentences with "I" or "we," and is often found in suggestions, such as "Shall we go?" "Shall" is also frequently used in promises or voluntary actions. In formal English, the use of "shall" to describe future events often expresses inevitability or predestination. "Shall" is much more commonly heard in British English than in American English; Americans prefer to use other forms, although they do sometimes use "shall" in suggestions or formalized language.

• Shall I help you? suggestion
• I shall never forget where I came from. promise
• He shall become our next king. predestination
