Why People Confuse Them
The wrong spelling heirarchy looks believable because heir is a real word. An heir is a person who inherits money, property, a title, or a role. Since a hierarchy can involve power, status, and rank, some writers mistakenly connect the spelling to heir.
But that connection is not correct for this word. The right spelling is always hierarchy.
Memory tip:
Hierarchy starts with h-i-e.
Think: hi-er-ar-chy.
