Question

make a word that means \the result of making something better.\

Explanation:

The suffix "-ment" is often used to form nouns from verbs. "Excite" is a verb. When we add the suffix "-ment" to "excite", we get the noun "excitement". But the meaning we need is "the result of making something better". The correct word - formation here is using the verb "improve" (which means to make better) and adding the suffix "-ment". So "improvement" means the result of making something better.

Answer:

improvement
