Questions & Answers about Nükleer santral güvenli.

What is güvenli doing in this sentence, and why is there no verb like “is”?

In Turkish, the present-tense copula “to be” is usually dropped. Here güvenli (“safe”) functions as the predicate adjective. The verb “to be” is understood rather than expressed, so Nükleer santral güvenli literally means “The nuclear power plant [is] safe.”

Why isn’t there an article like “the” or “a” before nükleer santral?

Turkish has no definite or indefinite articles. Context alone indicates whether something is definite or indefinite. Thus Nükleer santral güvenli can mean either “The nuclear power plant is safe” or “A nuclear power plant is safe,” depending on what you already know.

Why doesn’t nükleer santral take any suffix in this sentence?

As the subject of an equational (copular) sentence with an adjective predicate, nükleer santral stays in the nominative case and takes no case-ending. Only objects, possessives, locations, etc., need case suffixes.

How do I turn this into a yes/no question?

Add the question particle mi (in harmony with the preceding vowel) right after the adjective:
Nükleer santral güvenli mi?
That means “Is the nuclear power plant safe?”

How would I make the sentence negative?

Attach the negation –değil after the adjective:
Nükleer santral güvenli değil.
This says “The nuclear power plant is not safe.”

If I want to say “our nuclear power plant is safe,” what changes?

Attach the 1st-person-plural possessive suffix to santral:
Nükleer santralımız güvenli.
Here –ımız marks “our,” so it reads “Our nuclear power plant is safe.”

Can I use a more formal term for “power plant”?

Yes. enerji santrali (“energy plant”) is more formal/complete. You’d say:
Nükleer enerji santrali güvenli.
