The word 'rudimentary' means something that is basic or undeveloped. For example, if you are learning to play a musical instrument, you may have rudimentary skills or knowledge in the beginning, which means you are just starting to learn the basics. Another example could be a computer program that has only rudimentary features, meaning it's a very basic version with limited functions. Overall, 'rudimentary' can be used to describe anything that is in its early stages, basic or underdeveloped.
