Eligible vs Illegible Pronunciation

One reason people mix these words up is their similar appearance. Their pronunciation, however, is noticeably different.

Eligible Pronunciation

The middle sound resembles the “j” sound in “judge.”

Illegible Pronunciation

The stress falls on the second syllable, making it sound distinct from eligible.
