Propellor vs. Propeller: The Correct Spellings

Historically, the term "propeller" comes from the mid-19th century. As innovations in travel and transportation grew, the need for more advanced machinery became evident. The propeller, which uses its blades to push against air or water, became crucial for vehicles like boats and airplanes. Forms related to "propeller" include "propelled," "propelling," and "propulsive."

A useful way to remember the spelling of propeller is to think of the verb "propel." By simply adding the suffix "-er," which turns verbs into nouns denoting agents or things that perform an action, one can easily form the word. So, it’s "propel" + "er" = propeller. This association can be an effective mnemonic to ensure you never spell it as propellor again.

Choosing between propellor and propeller might seem confusing at first glance. However, the accepted spelling in American English is propeller. The word's origin is linked to the verb "propel," which means "to drive forward." When a suffix is added to a word ending in "l," it typically retains the single "l" unless the stress falls on the final syllable. Hence, propellor is a mistaken variant arising from inconsistent application of this rule.
