Thinking about derivation always gives a good headache because it is basically random. The same suffix doesn´t give the same meaning always, you can´t sum the meaning of the word from its constituents. The only thing you can usually see is the part of speech it represents.

Productive derivational suffixes are easier, though. Such as -li. I have understood but I am not sure that it attaches to just about any noun and in a certain context the result is always in place and the meaning can be understood even though you never heard the word before. It´s like something between derivation and inflection.

Yes -li suffix is just like a inflectional one. Another similar suffix is -lik in that regard.

In the grammar book which I read now four derivational suffixes are mentioned as productive:

1. N > N -li

2. N > N -lik

3. N > N -siz

4.a) V > N -(y)ici

b) N > N -ci

It seems that productive derivators are quite specific in meaning. You could almost translate them into English.
