Nomenclature Issue

It's basically: if a then b else c which is three parts.

And it’s by extension from binary operation, which is the standard term for the + in a + b.

I believe, Instead of ternary conditional operator it should be ternary conditional operation as three input operands is called ternary operation in mathematics

as

Operator is

• Types of operators:
• Arithmetic: +, -, *, /
• Comparison: ==, !=, >, <
• Logical: &&, ||, !
• Assignment: =, +=, -=

Operands is [a-z], [A-Z]

It brings confusion from Maths to Programming

in Swift https://docs.swift.org/swift-book/documentation/the-swift-programming-language/basicoperators/#Ternary-Conditional-Operator

It’s a conditional operator that takes three inputs, so calling it ternary conditional operator doesn’t seem like a big stretch.

Regardless, I’m not the person you need to convince here. If you want to discuss this with Swift language folks, I recommend that you bounce over to Swift Evolution.
