Questions & Answers about Bu veriler bilgisayarda depolanıyor.
In Turkish, bu can mean both this and these. It does not change for singular vs. plural.
So:
- bu veri = this piece of data / this data
- bu veriler = these data
The plurality is shown by veriler (veri + -ler), not by changing bu.
Veriler comes from:
- veri = data
- -ler = plural suffix
So:
- veri = data
- veriler = data / pieces of data / the data in a plural sense
A small note: in modern Turkish, veri is often treated a bit like an uncountable noun in some contexts, but veriler is also very common when talking about multiple data items or a set of data.
