For pentesting it can be usefull to have predefined wordlists which can be used for discovery (folders and stuff) or passwords.

Most PenTesting Distributions already deliver many wordlists.

Parrot OS has those in the /usr/share/wordlists but sometimes you want more than the default

Here are some good ones as addition to the existing ones:

SecLists:

Here you can find password, Fuzzing, Web directory lists and many more
