Questions & Answers about Güzellik hayatta en önemli şey değil.
How does the -lIk suffix change the meaning of güzel in the word güzellik?
The suffix -lIk turns adjectives or nouns into abstract nouns. Here, it attaches to the adjective güzel (beautiful) to create the noun güzellik (beauty). It takes the specific form -lik here because of 4-way vowel harmony (the last vowel in güzel is e).
Why is the locative suffix -ta instead of -da in hayatta?
This is a refresher on consonant mutation (often remembered by the rule "Fıstıkçı Şahap"). The word hayat (life) ends in a hard, voiceless consonant (t). When a suffix starting with d is added to it, the d hardens into a t to match. So, hayat + da becomes hayatta (in life).
How is the superlative ("the most") formed in this sentence?
To say "the most [adjective]" in Turkish, you simply place the word en before the adjective. Since önemli means "important", putting en in front makes en önemli (the most important).
