PARASKEVIDEKATRIAPHOBIA OR TRISKAIDEKAPHOBIA

This is reprinted from Sue's News from 2017: 

     FRIDAY THE 13TH

Each year there is at least one Friday the 13th;  2017 with two;  2012 and 2015 had the rare occasions of three dates of Friday the 13th;  there will be two in 2018.

As I am NOT superstitious, just for giggles and grins, I always say that 13 is my lucky number.  

                          PARASKEVIDEKATRIAPHOBIA

Recently a friend told me that I was incorrect in writing that TRISKAIDEKAPHOBIA is the term for the fear of Friday the 13th;  the actual correct word is PARASKEVIDEKATRIAPHOBIA.

See the article from The Urban Dictionary:  I especially like the last line:  "Though it has a serious use in psychology, it seems to exist mostly to provide an opportunity like me to show off  weird words from classical languages."

TRISKAIDEKAPHOBIA

Fear of the number 13.  

Strictly, the word does refer only to fear of the number 13, but it’s often extended to mean fear of the inauspicious date Friday 13th.  Every year has at least one Friday the 13th.   The word’s origins are all Greek, from tris, “three”, kai, “and”, deka, “ten” (so making thirteen), plus phobia, “fear, flight”. The word is a modern formation, dating only from 1911 (it first appeared in I H Coriat’s Abnormal Psychology). Though it has a serious use in psychology, it seems to exist mostly to provide an opportunity for people like me to show off weird words from classical languages. I'm triskaidekaphobic (no I'm not).
