Out loud and aloud sound very similar: however, they are both used in different situations. Back in the day, aloud was seen to be the only proper way to describe something you hear, such as a church sermon or a college lecture. The use of aloud is considered to be old fashioned and archaic. However, out loud is acceptable to use on Facebook and blog posts. Aloud is an adverb with a few different meanings. It could mean to say something louder than you would typically say it. It could also mean that you say something out loud that you are thinking in your mind. In this instance, out loud tends to fit better than aloud. It all depends upon the condition of the situation.
