Definitions:

(1) (gender as in: gender discrimination)
male or female

or (especially regarding self-identification): the state of being male, female, or in any of many trans categories

While the word sex can almost always be substituted for this meaning of gender, gender is typically used in reference to cultural or social differences, while sex is typically used for biological differences.

Less commonly, gender can refer to a grammatical categories. In some languages (not modern English), nouns that are not distinguishable by biological sex, can still have a feminine or masculine gender.
