How do major directories store their data?

Question

MySQL

I want to create a dictionary of English words for myself. As you learn the language, replenish it. I wanted to use MySQL, like this:

Rating for the survey.
But somewhere I read that dictionaries use some other databases with other architecture, not relational. I wanted to clarify, what if the database grows by 10,000 words or more? Will it slow down? And what DBs usually use large dictionaries?

For 10,000, and even for 100,000 - enough.
But I would advise to reconsider architecture of a DB. Because such an architecture at least does not allow to store different translation options normally. More precisely, you can store it, only there will be more data.
