The phrasal verb 'keep back' is more frequently found in informal contexts but can occasionally appear in formal speech. It primarily means to reserve or retain something, such as money or emotions, and not disclose or spend it entirely. For example, one might 'keep back' a sum of money for unforeseen expenses or 'keep back' their true feelings in a delicate situation. This phrasal verb is often used when discussing matters of behavior, finances, or personal matters where withholding or reserving something is implied. Its usage in conversation typically revolves around the need to economize, control emotions, or withhold information deliberately. Additionally, in class-based or institutional contexts, 'keep back' can also imply holding someone at a level or preventing advancement, such as in education where a student might be 'kept back' a grade due to not meeting the required standards.
