Root Explanation

Collinearity is formed from "col-" (meaning together) and "linea" (meaning line) combined with the suffix "-arity" (indicating a state or condition). The term describes the state of points lying on the same line, hence, being together on a line.

Memory Tip

Think of points being 'together' ('col-') on a 'line' ('linea') — that's what collinearity means.
