It is difficult to write a PSA or a Public Service Announcement that operates in just sixty (60) seconds because you have to consider a lot of factors into writing it. First, you consider what message you want to convey. Second, you consider what kind of audience you're targeting. Lastly, you have to make sure that the PSA will effectively convey the message to the target audience in such short amount of time.
Suffixes are letters or group of letters which are added at the end of a specific word which results to a new word. This new word usually has a different class than the original term. Examples are -ful in forgetful and useful, -ment in statement and government, -ion in creation.
