Totemo / Zuibun - Very / Extremely
Yoku - Often
Amari - Seldom
Zenzen - Totally / Not at all

Examples
That car is very expensive - Sono kuruma wa totemo takai desu.
I write letter very often - Tegami o yoku kakimasu
I seldom drink coffee - Ko-Hi- wa amari nomimasen
I don’t smoke cigarette at all - zenzen suimasen

You may notice that there is an “o” in the second example. In hiragana, the “o” is を instead of お. Don’s mix them up. When you are typing the “o”, you should type as “wo” instead of “o” but pronunciation wise, it should be pronounced as “o” or some people say “wo”.

“o” is a particle and used for indicating the case role of the phrase in relation to another word (used especially as a direct object marker). Example : I drink water will be translated as “Watashi wa mizu o nomimasu”. You are doing something to something. In this case, you are drinking the water. Another example : Denwa o kakemasu (Make a telephone call), Mado o shimemasu (Close the window)…..

Try it yourself with different phrases. It’s a good practice though.
