Triskaidekaphobia – Irrational fear of the number thirteen

Triskaidekaphobia is a combination of multiple Greek words. Τρεῖς (tres) three, χαί (kai), δέχα (deka) ten and, or course φόβος (phobos) fear.

This word came up in a Greek class this morning, as we were learning the numbers.

Triskaidekaphobia explains why some high rises do not have a thirteenth floor.

I suspect I may have triskaidekaphobia as my own home does not have a thirteenth floor. Or, twelfth, eleventh, tenth, ninth, eighth, seventh, sixth, fifth, fourth, or third. Turns out, I may have an irrational fear of multiple numbers.


Almost every Saturday, I send out a Tip of the Week.  The tip of the week is usually 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 digital copy of my book on learning Latin (and almost anything else).  Just go here:

If you want to buy the digital book instead (because you just feel like buying me a cup of coffee) go here:

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:

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.

I teach other languages on my site, too.  The current schedule is here:
