Define the following word using the meaning of the suffix. Use your dictionary if you are uncertain of the definition. Argument

a. full of disagreement

b. act of disagreement

c. state of disagreement

d. quality of disagreement

The suffix here would be 'ment', which means 'an act of, a state of, or a result of'. The suffix 'ment' changes the word from a verb to a noun, therefore to argue is a verb and becomes an argument which is a noun, to disagree is a verb and becomes a disagreement which is a noun. Therefore to define argument using this logic and one of the four options given the correct answer would be C. state of disagreement.

b. act of disagreement

Explanation:

The suffix in "argument" will be "-ment". 'Argue' is a verb and with the addition of the sufix - ment, it becomes a noun. Likewise, to disagree is a verb but with the suffix - ment, it changes into a noun "disagreement". So, "argument" can also be defined as an act of disagreement, representing the literal act of argument.
