I learned many great things from all parts of speech.
In the noun section, I learned the rule of changing F to V when making plurals.
In the verb section, I understood the different types of verbs.
The most interesting and enjoyable part for me was the section about interjections — I learned amazing words like:
Ew, Ick, Ugh, Ow, Aww, Aha, Shhh...
I learned that conjunctions are divided into three types.
It was interesting and very informative to learn about the coordinating conjunctions represented by the abbreviation FANBOYS.
