Questions & Answers about Jeśli nie zapomnę o skierowaniu, jutro rano znowu pójdę do laboratorium.
Yes. Jeśli and jeżeli both mean if.
- jeśli is very common and natural in everyday speech
- jeżeli can sound a bit more formal or careful
In this sentence, Jeśli nie zapomnę o skierowaniu... means If I don't forget the referral...
Both are correct here.
Because zapomnę comes from the perfective verb zapomnieć, and it refers to a single completed future event: I will forget.
Compare:
- zapomnieć → perfective → zapomnę = I will forget
- zapominać → imperfective → zapominam = I forget / I am forgetting / I tend to forget
Here the speaker is talking about one possible future situation, so nie zapomnę is the natural choice.
