In Spanish, 'perífrasis verbales' are combinations of two or more verbs that express ideas like obligation, possibility, or probability. These constructions help you talk about what must be done, what might happen, or what is likely.
Use these forms to talk about duties (what someone has to do), possibilities (what someone can do), and probabilities (what is likely to happen) in Spanish. They help you express necessity, permission, and uncertainty.
