Pronunciation is the term which refers to how correctly a word is said.
Explanation:
Pronunciation is the act of speaking a word correctly. For example, speaking the word "nu-cle-ar", is the correct way of pronouncing it and speaking it as 'nu-cu-lar' is incorrect. It is term we use for how correctly a word is said. When we pronounce words correctly, it increases our credibility in the language we speak. Just as an essay doesn't look good with spelling errors, a speech with pronunciation errors doesn't have a lasting effect on the audience.
Pronunciation is different from articulation. Articulation is how clearly a word is said.
