How do you spell illogical?

Syllables: il - log - i - cal

Tricky part: The prefix il meets another l, so the word starts with a double l.

Watch out for: ilogical, illodgical, illojical

Memory tip: Before a word starting with l, the prefix for not becomes il, as in illegal, so this word opens with two l's.

Illogical in a sentence

Example 2: His excuse for being late sounded completely illogical.

Example 3: Fearing the number thirteen is illogical, but many people do.

Fun Fact

Illogical goes back to the Greek word logos, which meant word or reason, so an illogical idea goes against reason.
