Aberration
noun/ab-uh-ray-shuhn/
a departure from what is normal, usual, or expected, typically one that is unwelcome.
In contextThe snow in April was an aberration for the region.
Remember it
An aberration is an 'error-ation' — a one-off that strays from the normal pattern.
Use it well
Use for a one-off oddity, not a habit: 'just an aberration' reassures that normal service will resume.
