Okay kiddo, have you ever tried to build something with legos, but didn't have the right pieces? So instead, you used other pieces that didn't really fit, but you made it work anyway? That's kind of like what a kludge is!
A kludge is when people try to fix something or make something work, but they don't have the proper tools or resources to do it the right way. So they use things in kind of a makeshift or temporary way to get the job done, even though it might not be the best solution.
The word "kludge" is usually used when talking about technology or computer software. For example, if a programmer is trying to fix a computer program and doesn't have all the necessary code or time to fix it correctly, they might use a kludge to make it work temporarily until they can come up with a better solution.
It's kind of like a band-aid for a bigger problem, it doesn't fully solve the problem, but it makes it work for the time being.
