What is the greek word for those?

The Greek word for "those" depends on the gender and number of the nouns it refers to. There isn't one single translation. You need to specify:

* Masculine, Feminine, or Neuter: Greek nouns have genders.

* Singular or Plural: Is it one thing or multiple things?

For example:

* Masculine plural: ἐκεῖνοι (ekeinoi)

* Feminine plural: ἐκεῖναι (ekeinai)

* Neuter plural: ἐκεῖνα (ekeina)
