Explanation:

In the English language, especially when it comes to words originated from Latin, it is common to change words with the addition or removal of certain parts -- the affixes. Notice, for example, that to transform "vulnerable" into a noun, we added a suffix (an ending): "vulnerability". On the other hand, to transform "censorship" into an adverb, we changed suffixes: "censorious". It is important to know and understand the use of affixes. They are a helpful means to figure out the meanings of new words.
