Pronunciation: [ɡˈe͡ɪpə] (IPA) 
The word "Gaper" can sometimes be confusing when it comes to spelling. The correct pronunciation is /ˈɡeɪpər/, which is why it can be spelled with either one "a" or two. The word means someone who stares openly and foolishly. It could be a person who's overly curious or just staring off into space. It's an informal word that may not be used commonly but its spelling and pronunciation are interesting nonetheless.
Gaper is a noun that refers to a person who openly stares or gapes at something or someone with a sense of curiosity, wonder, or astonishment. The term is often used to describe someone who is observed as staring in a silly, foolish, or clueless manner, usually indicating a lack of awareness or understanding of their surroundings.
The term "gaper" can also specifically imply a person who is caught in a state of open-mouthed astonishment or a foolishly excessive interest in something. This behavior can often be displayed in public places, such as tourist spots or events, where individuals become transfixed by the sights or sounds before them.
This term is derived from the verb "to gape," which means to stare openly or with an open mouth due to surprise, amazement, or ignorance. The word "gaper" itself originated in the English language around the 16th century and has since maintained its usage to describe individuals who are visibly engrossed or captivated by something, often to the point of being oblivious to their surroundings or the potential social implications of their behavior.
In contemporary usage, the term "gaper" may also be applied derogatorily to indicate a person who is slow to react or comprehend a situation, or someone who is easily fooled or deceived due to their naivety or lack of knowledge.
One who stares foolishly.

The word "gaper" has two main etymological origins, each with a slightly different meaning.
1. The term "gaper" originates from Middle English and comes from the Old Norse word "gaup", which means "to stare" or "to gape". In this sense, a "gaper" refers to someone who stares open-mouthed or with wonder. It can also imply someone who is foolish or absent-minded, someone who is easily surprised or amazed.
2. Another usage of "gaper" comes from the Dutch word "gaper" meaning "a person with an open mouth". In Dutch culture, a "gaper" refers to a traditional wooden sculpture or sign often seen hanging outside pharmacies. These sculptures depict the head of a Moor, usually with open mouth, and were traditionally used to attract customers to the pharmacy.
