Questions & Answers about Ο κωδικός PIN δεν λειτουργεί· ελέγξτε το έμβασμα και τη συναλλαγή.
Because the head noun here is κωδικός (code), and PIN works like a label specifying what kind of code it is.
So:
- ο κωδικός = the code
- PIN = a modifier, like PIN in English PIN code
The article ο agrees with κωδικός, which is masculine singular.
In everyday Greek, people may also simply say το PIN, but ο κωδικός PIN is a very normal full form, especially in banking or technical language.
Only κωδικός is inflected here. PIN is treated as an indeclinable foreign abbreviation.
So Greek grammar shows up on the Greek word:
- nominative: ο κωδικός PIN
- accusative: τον κωδικό PIN
- genitive: του κωδικού PIN
The PIN part normally stays the same.
