What does orthogonal mean?
When lines are perpendicular, they intersect or meet to form a right angle. For example, the corners of squares and rectangles are all right angles.
However, orthogonal is also sometimes used in a figurative way meaning unrelated, separate, in opposition, or irrelevant. In this sense, it means about the opposite of parallel when parallel means corresponding or similar.
Example: Not everything happens according to a grand scheme—some events are simply orthogonal to each other.
Where does orthogonal come from?
The first records of orthogonal in English come from the 1500s. It ultimately comes from the Greek orthogṓnion, meaning “right-angled (shape).” This Greek root is composed of the elements ortho-, “straight, upright, right,” and –gōnion, “angled.”
Orthogonal is commonly used in mathematics, geometry, statistics, and software engineering. Most generally, it’s used to describe things that have rectangular or right-angled elements. More technically, in the context of vectors and functions, orthogonal means “having a product equal to zero.”
More recently, orthogonal has come to be used in a figurative way. It’s typically applied to two things to describe them as independent of or irrelevant to each other. Sometimes it implies that they are in opposition to each other in some way, perhaps because they have divergent goals or outcomes or causes.

How is orthogonal used in real life?
Orthogonal is commonly used in the context of things designed with right angles. It’s figurative use is often applied to events considered unrelated to each other.
@GoodNotesApp big kudos for the new shape tool improvements. Been waiting for ages on this. While a whole lot better, maybe the degree of orthogonal filtering could be adjustable? this would be useful for drawing squares/rectangles

There is the demographic in power, threatened with losing power, fighting to preserve it. There is an unwieldy coalition of outsider demographics, fighting to spread the power/money/privileges more broadly & fairly. The "size of gov't" debate is orthogonal to that, a sideshow.

That's the thing. My friends in history will tell you that the present makes enormous efforts to ignore, forget, lie, cheat, or otherwise condemn the past. The present has typically an orthogonal relationship with the past. Disease straightens the relationship.
