Quick Answer:
A real-world example of supervised learning is a spam filter in an email client. The filter is trained on a labeled dataset of emails, where some are classified as spam and others as not spam. The filter then uses this labeled data to make predictions on new, unseen emails by comparing their characteristics to those in the training data. If the filter determines that an email is similar to known spam, it will label it as spam; if it resembles a legitimate email, it will allow it through. This process of training a model on labeled data and using it to make predictions on new data is the essence of supervised learning.
