An atavistic trait is a trait you picked up from your ancestors. It skipped a generation, or two, though. Your parents did not have this trait. Atavistic traits disappear for a time only to show up later. For example, “He has an atavistic temper. It comes from his grandfather.”
Atavistic comes from the Latin word atavus meaning ancestor, forefather, or great-great-great grandfather.
Almost every Saturday, I send out a Tip of the Week. It’s just something I have picked up along the way that may make your life a little easier. If you would like to hear from me (almost) every Saturday, just go to the home page of my site and plug in your name and email. You will also get a free copy of my book on learning Latin (and almost anything else). Just go here: https://dwanethomas.com/
If you are interested in learning Latin, you can go through the classes on my site 24/7. I recommend the book Lingua Latina by Hans Ørberg. If you tackle the book and find yourself bogged down, you may find the classes on my site helpful. To join, just click here: https://dwanethomas.com/join/
If you want a more professionally filmed experience, check out the best-selling DVD series: Visual Latin.
Or, if you want to skip Latin, and just jump right into learning English words from Latin and Greek roots, you may enjoy the series Word Up! Warning. Word Up! is a bit wacky. You will learn a lot… but, you may find yourself rolling your eyes, too.
