Bundle of principal parts

A bundle of principal parts is like a group of super important words that you need to know if you want to speak a language really well. Just like how you need to know your ABCs and numbers from 1 to 10 really well before you can read and do math, you need to know these principal parts really well before you can speak a language really well.

These principal parts are usually verbs, which are action words like "run," "jump," and "eat." But they're not just any verbs - they're the most important verbs in a language because they can help you understand and use other verbs that are similar to them.

For example, in English, the verb "to drive" is a principal part because it can help you understand and use other verbs like "drove," "driven," and "driving." These words are all related to "drive" and they all have different meanings depending on how they're used.

So, imagine if you had a big bundle of all the most important verbs in a language, like "drive," "run," "play," and "eat." You would have a much easier time understanding and using other verbs that are related to them. And that's what a bundle of principal parts is - a group of super important verbs that can help you speak a language really well.
