Questions & Answers about Merdivenin eğimi çok dik.

Why is there no word for “is” in Merdivenin eğimi çok dik?

In Turkish the present-tense copula “to be” is usually omitted. You simply state X çok dik to mean “X is very steep.”

What roles do the suffixes -in in merdivenin and -i in eğimi play?

-in marks the genitive case (corresponding to English of), so merdivenin = of the ladder/stairs.
-i is the 3rd-person singular possessive, turning eğim (slope) into eğimi = its slope.
Together merdivenin eğimi = the ladder’s slope.

Can I just say merdiven eğimi instead of merdivenin eğimi?

No. To express “the slope of the ladder,” Turkish requires genitive on the possessor (merdivenin) and possessive on the possessed (eğimi). Omitting them is ungrammatical or ambiguous.

Which part of the sentence is the subject and which is the predicate?

Merdivenin eğimi is the subject (the thing being described), and çok dik is the predicate adjective (describing how steep it is).

Why is çok placed before dik? Could it go after?
