How to spell idiosyncrasy

idiosyncrasy

Idiosyncrasy is spelled I-D-I-O-S-Y-N-C-R-A-S-Y.

Not idiosyncracy.

Why is idiosyncrasy easy to misspell?

Same sound, different letters

The word idiosyncrasy ends -sy, and the misspelling idiosyncracy gives it the -cy of democracy. The words for kinds of rule end -cracy, and this one is not among them.

That spelling matches the sound exactly, which is why it looked right. English keeps letters long after the sound has moved on, so the conventional spelling is often the one that looks least like it sounds.

Greek spelling: y for the i sound between consonants
