Questions & Answers about Aslında o pek iyi değil.
Why use pek instead of çok for "very"?
While çok means "very" or "a lot," pek is a special word for "very" that is mostly used in negative sentences. Because this sentence ends with the negative word değil (not), it is much more natural to say pek iyi değil rather than çok iyi değil.
How do we know o means "he" and not "she"?
We don't! Turkish does not have gendered pronouns. The word o means "he", "she", or "it". The translation here uses "he", but without more context, it could just as easily mean "Actually she is not very well."
Where is the word for "is" in this sentence?
I recognize the -da ending on aslında. Is that the "in/on/at" suffix?
Yes, it is! The root word is asıl (origin, essence, or reality). When you add the suffixes, aslında literally means "in its reality" or "at its essence"—which is exactly how Turkish speakers say "actually" or "in fact."
