Questions & Answers about Sayaç okuması yanlış görünüyor.
This is because sayaç okuması is a common Turkish noun compound. In this pattern, the first noun stays plain, and the second noun takes the 3rd person possessive suffix.
So:
- okuma = reading
- okuması = its reading
The -sı appears because okuma ends in a vowel, so Turkish uses a buffer s before the possessive ending.
Not in the usual ownership sense. In Turkish, this possessive-looking form is very often used just to build compound nouns.
So sayaç okuması does not strongly mean the meter’s reading in an English possessive sense. It simply means meter reading as a set expression.
