What does correct enuncation mean

Make sure your enunciation is clear when ordering in a restaurant so you don't get French flies instead of French fries. Enunciation is from the Latin word enuntiationem, meaning "declaration." Enunciation is more than pronouncing words clearly; it's expressing them well, too.

It means to pronounce speech properly, with clarity. For example, the correct enunciation of "clarity" is cla-ree-tee in phonetic form.
