ものか

ものか is used to express strong denial or a rhetorical question about the possibility or likelihood of something. It often sounds emphatic, challenging, or admonitory. It can express disbelief, a warning, or a sense that something is unthinkable, with nuance like “There is no way ~,” “Who would ~?,” or “As if I would ~.” It is more common in formal, literary, or emphatic spoken styles and can appear in both serious and light admonitions depending on context.
