Questions & Answers about Στο τετράδιό μου γράφω και ένα συνώνυμο για κάθε καινούρια λέξη.
Στο is a contraction of σε + το.
- σε = in / at / to, depending on context
- το = the for a neuter singular noun
So:
- στο τετράδιό μου = in my notebook
In this sentence, στο means in.
This is because μου is an enclitic word, meaning it is unstressed and leans on the word before it.
The noun τετράδιο is stressed on the third syllable from the end. When a word like that is followed by an enclitic such as μου, Greek often adds an extra written accent:
- τετράδιο
- τετράδιό μου
So τετράδιό μου means my notebook.
This extra accent does not mean the word suddenly becomes a different word. It is mainly a spelling rule connected with stress.
