Questions & Answers about Herkes staj yapıyordu, keşke ben de yeni beceriler öğrenseydim.
How does öğrenseydim show that this is a past regret?
It uses the formula for past regret: the conditional suffix -se followed by the past tense suffix -di. In öğrenseydim, we have öğren (learn) + -se (wish/if) + -y- (buffer letter) + -di (past) + -m (I). Together with keşke, this strictly means 'I wish I had learned' (but I didn't).
Why use yapıyordu instead of yaptı in the first part of the sentence?
yapıyordu combines the continuous suffix -ıyor with the past suffix -du. This translates perfectly to the English past continuous: 'was doing'. The speaker is setting a background scene of what was happening around them, making their regret feel more tied to that ongoing period.
Since the verb already ends in -m for 'I', why do we need the word ben?
Normally, you can drop the pronoun because the verb ending tells us who is acting. However, the speaker wants to say 'I too'. To use the 'too/also' particle (de), you need the standalone pronoun to put it next to: ben de.
