Why Is Hierarchy the Correct Spelling?
The word hierarchy has a historical origin in Greek, through Latin and French. Its spelling developed independently of the English word heir.
An heir is someone who inherits or is entitled to inherit something. A hierarchy, by contrast, is a structured arrangement of levels or ranks.
The similarity between the beginning of these words can cause confusion, but their spellings should not be mixed.
Remember these forms:
- Hierarchy: the correct word for ranked levels.
- Heir: a person who inherits property or a title.
- Heirarchy: an incorrect spelling of hierarchy.
Learning the distinction between hierarchy and heir makes it easier to avoid this common spelling mistake.
