The Comparison of Adjectives

The Degree of Equality

The degree of equality is obtained by the use of kadar.. - [Lit: "its amount"] - as..
Londra İstanbul kadar güzel. - London is as beautiful as Istanbul.
Mehmet Ali kadar zengin. - Mehmet is as rich as Ali.
Kar kadar beyaz. - As white as snow.

The Negative Equality

The negative comparison is marked by the use of - değil - is not - placed after the comparison.
Londra İstanbul kadar güzel değil. - London is not as beautiful as Istanbul.
Ayşe Deren kadar boylu değil. - Ayşe is not as tall as Deren.

The Degree of Comparison:

This comparison is made by using - daha - more - and suffixing the object being compared with -dan or -den - from - thus giving the sense than in the comparison.
Mehmet Ali'den daha zengin. - Mehmet is richer than Ali.
İstanbul Londra'dan daha güzel. - Istanbul is more beautiful than London.
Demir sudan daha ağır. - Iron is heavier than water.

The Negative of Comparison

The Negative First Degree Comparison uses daha az - less(er)
Londra İstanbul'dan daha az meşgul. - London is less busy than İstanbul.
Bulmacalar Türkçe derslerden daha az ilginç. - Crosswords are less interesting than Turkish lessons

The Positive Superlative

The Third Degree of Comparison is obtained by using en - the most
Mehmet en zengin adam. - Mehmet is the richest man.
Dünyanın en güzel şehri, İstanbul. - Istanbul is the world's most beautiful city.

The Negative Superlative

The Negative uses - en az - the least - [Lit: the most less..]
Dünyanın en az zengin memleketleri Afrika'da. - The least richest countries of the world are in Africa.
However, the fact is that although possible, usage of - en az - for negative superlatives is not common. The preferred way is to use the superlative form of opposite adjective. So, the preferred way of the example is:
Dünyanın en fakir memleketleri Afrika'da. - The world's poorest countries are in Africa.
