Here's why:
* Suffixes: These suffixes are often used to form nouns, indicating an action, process, or state.
* Examples:
* Association: (noun) a group of people who have joined together for a particular purpose
* Decision: (noun) a choice that you make after thinking carefully about the possibilities
* Attention: (noun) the act of focusing your mind on something
* Education: (noun) the process of teaching and learning
Exceptions:
While most "-sion" and "-tion" words are nouns, there are exceptions. Some words can function as adjectives:
* National: (adjective) relating to a nation
* Conditional: (adjective) depending on a condition
* Exceptional: (adjective) very unusual or good
It's important to consider the context of the word to determine its part of speech.
