Basilic is an adjective that means royal or of great importance.
The Greek word basilikḗ (BAH seal eek) means ‘royal building.’ As the word evolved through Latin and French, it retained the same basic meaning. To this day, a basilica may refer to a giant church. Our word of the day has a broader meaning that may refer to anything of giant significance.
Our boss is constantly reminding us of the basilic nature of this recent exhibit. He says its success would greatly enhance the museum’s reputation.
