Yeah, the very weak ones can be broken in seconds. There are websites where you can check how strong your password is such as: https://howsecureismypassword.net/

Try something similar to your password and see what it says, but merely using a dictionary word with a couple of symbols and numbers doesn't make it unbreakable but the longer it is with numerous symbols and numbers will make it much stronger. Ideally it should be some random gibberish with a lot of symbols and numbers and upper and lower case.
