Parameter

Definition

Parameter refers to a numerical or other measurable factor forming one of a set that defines a system or sets the conditions of its operation.

Parts of Speech

• Noun: parameter (e.g., "The function takes two parameters.")

Pronunciation

American English

• IPA Pronunciation: /pəˈræmɪtər/
• Respelling: puh-RAM-i-ter (with "puh" as in "cup," "RAM" as in "ram," "i" as in "sit," and "ter" as in "water")

British English

• IPA Pronunciation: /pəˈræmɪtə/
• Respelling: puh-RAM-i-tuh (similar to American English, with "puh" as in "cup," "RAM" as in "ram," "i" as in "sit," and "tuh" as in "butter")

In both dialects, "parameter" places the primary stress on the second syllable, "RAM." The pronunciation reflects typical regional variations in vowel sounds and pronunciation style between American and British English, focusing on the clear articulation of the "RAM" part followed by "i" and then "ter" or "tuh."

Etymology

The word "parameter" is derived from the New Latin parametrum, which originates from the Greek "para-" meaning "beside" and "metron" meaning "measure". In essence, it implies something that is measured alongside something else.

Detailed Definition

Noun

• A value or set of values that define a function or system, often used to determine the behavior or outcome of a procedure.
• Example: "In the equation 𝑦=𝑚𝑥+𝑏y=mx+b, 𝑚m and 𝑏b are parameters that represent the slope and y-intercept of the line, respectively."

• A defining characteristic or factor; something that restricts or shapes outcomes.
• Example: "The parameters of the debate were set beforehand."

• In computing, a value passed to a function or method when it's called, used to influence the operation of the function.
• Example: "The function requires three parameters: a, b, and c."
