If you are finding terms that you do not know what they mean when you first come across them in the notes you can search on them in the notes to see if they are covered later. For example, reasonable assurance (page 28) and materiality (page 32).
If you don’t find words explained as terms having a specific technical meaning, they are probably just “normal” words. You should find this site useful https://www.merriam-webster.com/ – put the word in the search box at the top for dictionary definitions.
