Questions & Answers about Kuruluştan beri bu şirkette çalışıyor.
How do we say "since" here, and why does kuruluş have the -tan ending?
The word for "since" is beri. In Turkish, beri always requires the word before it to have the "from" (ablative) ending. So we take kuruluş (foundation), add the ending -tan, and use beri to make the phrase kuruluştan beri (since the foundation).
Why is it kuruluştan and şirkette instead of -dan and -de?
Both kuruluş and şirket end in hard consonants (ş and t). Because of consonant harmony, the suffix must start with a hard consonant to match. So the "from" ending -dan becomes -tan, and the "in" ending -de becomes -te.
Where is the word "its"? The English translation says "since its foundation".
Turkish often drops possessive words like "its" when the context makes it obvious. Here, kuruluştan literally just means "from foundation", but it naturally implies the foundation of the company being discussed.
The English says "has been working", but çalışıyor is the present continuous tense. Why not use a past tense?
In Turkish, if an action started in the past and is still happening right now, you just use the present continuous tense (-ıyor). English uses a special tense for this ("has been working"), but Turkish focuses on the fact that she is still working there today, so it stays in the present tense.
