scheme
About scheme or [schema
Latin for "form."
highly abstract
Someone who wanted to refer to a "form" in some specific sense, but wanted to distinguish it from the "form" (form) of everyday speech, used the Latin vocabulary
The "object" in object-oriented design is a "thing", but we don't want to call it a "thing", so we call it an object in English.
This was done by different people in different fields, so the word has become difficult to understand the meaning.
From Medieval Latin schēma (“figure, form”), from Ancient Greek σχῆμα (skhêma, “form, shape”), from ἔχω (ékhō, “I hold”). Doublet of schema. Compare sketch.
