The phrasal verb "cave in" is primarily used in informal contexts to describe situations where something collapses or gives way under pressure, either literally or figuratively. In literal usage, it often refers to physical structures like roofs, tunnels, or mines collapsing due to inadequate support or external forces, and it's commonly found in discussions related to engineering, mining, or natural disasters. Figuratively, "cave in" is used to describe a person yielding to pressure, demands, or emotions, signifying a loss of resistance or the succumbing to persuasive forces. This usage is prevalent in conversational English and is used in various contexts, including interpersonal relationships and negotiations. While it's most frequently encountered in everyday speech and informal writing, the figurative sense of the term may occasionally appear in more formal discourses, particularly when discussing social dynamics or psychological states.
