validate

To validate something is to confirm that it is correct, acceptable, or real. Think of a parking attendant validating your ticket: they are marking it so it counts. But the idea goes beyond tickets. When someone validates your feelings, they show that your experience is real and understandable. A scientist validates a result by finding evidence that supports it. In each case, the word is about giving something proper support, approval, or recognition. If your friend says she feels sad, a validating response might be, "That sounds really hard; I can see why you feel that way."

To validate means to confirm, support, or officially accept something as sound, proper, or real. It can be used in many settings, from formal procedures to personal conversations. At its core, the word is about giving something solid backing.

In technical fields, validation often means checking that something meets certain requirements. A software developer might validate user input before a form is submitted. Scientists validate results through repeated testing and observation. An engineer validates a design before construction begins.

But validation is not just about facts and systems; it is also important in human relationships. When you validate someone's feelings, you show that their experience makes sense, even if you do not fully agree with their opinion or reaction. For example, saying "I can see why you would feel frustrated in that situation" is a way of validating someone's emotions.

You might also hear about the human need for validation, meaning a desire to feel seen, accepted, or approved of by others. In other contexts, people speak of validation when they want proof that an idea, method, or decision really works.

So, whether it is marking a parking ticket, checking research results, approving a process, or acknowledging someone's feelings, to validate is to give confirmation, acceptance, or support.
