For a cousin older than you:
* Tuaine: older male cousin
* Tuahine: older female cousin
For a cousin younger than you:
* Teina: younger male cousin
* Teina: younger female cousin
For a cousin of the same age:
* Whiti: same-age cousin (regardless of gender)
It's important to note that these terms can be used for cousins on either your mother's or father's side of the family. The specific relationship can be clarified by adding the appropriate prefix:
* Tūpuna: ancestor (often used to refer to a grandparent)
* Matua: father (often used to refer to an uncle)
* Whaea: mother (often used to refer to an aunt)
For example, "Tūpuna whaea" would refer to your mother's sister (your aunt), while "Matua tuaine" would refer to your father's older brother (your older uncle).
Therefore, the best way to translate "cousin" in Māori is to specify the age and gender of the person you are referring to.
