The definition of a term

Answer 1

A term is a constant, a variable, or combination of constants and variables.

Examples:

7.13,

5x, where 5 is the coefficient of the variable

xy,

xyz,

y, where the coefficient of the variable is assumed to be 1.

Answer 2

A term labels or designates concepts. Several partly or fully distinct concepts may share the same term. These different concepts are easily confused by mistakenly being used interchangeably, which is a fallacy. Also, the concepts of term and concept are often confused, although the two are not the same.

In Canadian high school, a term is a semester.
