Pronunciation: [ˈɒblɒŋ] (IPA) 
The spelling of "oblong" can be confusing, as it doesn't follow the typical English pattern for phonetic sounds. The word is pronounced /ˈɑːblɒŋ/ (AH-blong), with a longer "o" sound than expected and an unusual "bl" sound. The word refers to something that is longer than it is wide, such as a rectangle. Despite its unusual spelling, "oblong" is a common word used in mathematics and geometry, as well as in everyday conversations.
Oblong is an adjective used to describe a shape that is elongated or elongated in one direction, where the length is considerably greater than the width. It refers to an object, figure, or form that is rectangular or nearly so, with its longer sides being parallel to each other. The term oblong is derived from the Latin word "oblongus," which means "rather long" or "lengthened."
In mathematics and geometry, an oblong shape is often characterized by having two pairs of equal-length sides, opposite sides being parallel, and right angles at the corners. It can also be seen as a rectangle with unequal sides, as long as the longer sides are parallel. The proportions of an oblong can vary, and the term encompasses a wide range of rectangular shapes, including rectangles and squares.
Beyond its mathematical definition, oblong is also commonly used to describe various objects in daily life that possess an elongated or rectangular shape. These can include oblong fruits like bananas or watermelons, oblong tables, oblong structures or buildings, oblong containers, and many others.
Overall, oblong serves as a descriptive term that aids in distinguishing elongated rectangular shapes from other regular or irregular geometrical figures, emphasizing their characteristic elongation along the longer axis.
• A figure longer than broad.

The word "oblong" is derived from the Latin term "oblongus", which combines the prefix "ob-" (meaning "against" or "in the way of") with the word "longus" (meaning "long"). Thus, "oblongus" implies something that is longer in one direction compared to its width. The term was later adopted into Middle English and has been used to describe elongated shapes or rectangles ever since.
