What is ise?

The Turkish word ise can have two different meanings and we usually see it as a suffix -se/-sa.
If it is added a word that has a,ı,o or u as last vowel, we choose -sa, and if it is e,i,ö or ü then we choose -se.

1) Conjunction
It can be used together with the word "eğer" but it is enough just to add -se/-sa

2) Comparison
It builds a comparison and strengthens it.
