The phrasal verb "break off" is commonly used in informal speech and less frequently in formal contexts. It typically means to suddenly stop speaking or to end something abruptly, such as a conversation, relationship, or agreement. For example, one might "break off" a sentence mid-way due to an interruption or "break off" a romantic relationship if things aren't going well. In formal settings, "terminate" or "discontinue" might replace "break off" for a more official tone. It can also refer to a physical detachment, such as a piece of bread breaking off from the loaf or part of a structure detaching. The verb's usage is relatively versatile, appearing in both personal and business contexts, though its casual nature leans it more towards everyday speech.
