There is a high-quality list of semi-random words for people to use in passwords. It was crafted by the Electronic Frontier Foundation in 2016 and is free to use:

Now, you might think that having a list of words expected to be used in passwords, that is published on a major resource, could be kind of counterproductive for security if it's widely adopted. But here #EFF actually recommends using passphrashes - combinations of these words, and that means they're exponentially harder to crack. But then the problem of character count arises. I don't know a lot of sites where you can set a 30 character long password.
But, at the end of the day, it's your password and you can easily make a neat and rememberable by getting rid of excess words etc. The distinctive feature of this list is that it has common, user-friendly words, that are memorisable by anyone pretty quickly. So if anything, have that for your reference.
