- suffix Used in forming names of countries, diseases, flowers, and rarely collections of things (such as militaria, deletia).
- suffix Used in forming plurals of nouns in -ium and -ion.
The ending -ia would indicate Ya, short for YHWH or Yaweh, the other biblical name for God, generally translated "Lord."
The name tags had been specially prepared: a blank space for your name on the first line, the printed words A Person With on the second, and on the bottom line you were supposed to print the name of your phobia, using the -ia suffix, not the -ic.
