To add information about a person or thing, join the clause with που — it works for people and objects alike and never changes for gender, number or case. It covers English "who", "which" and "that".
Examples
- Η δουλειά που κάνω είναι απαιτητική.
- The job I do is demanding.
- Ο συνάδελφος που δουλεύει μαζί μου σπούδασε στη Γερμανία.
- The colleague who works with me studied in Germany.
- Οι σπουδές που διάλεξα με βοήθησαν πολύ.
- The studies I chose helped me a lot.
The mistake to avoid
Reaching for ο οποίος every time — it exists but is formal; in speech που is the normal choice.
Where this fits in
Δουλειά και σπουδές, Greek B1: Talk about your job, workplace, and studies; give reasons and opinions.
