Translation of smother in Spanish

I will usually use the most usual sense of the term, and not the more sophisticated ones and I think you will understand what I wanted to say. In any case we should review all words every two days or so.
If I look at dictionaries they do not give long sentences, only specific words and their meaning when they are used in a compounded form, which by the way can mean something totally different than when used by themselves.
I have been studying Hungarian for one month. I also speak English, German and Latin. Hungarian would be my fourth language, and it gives me headache. I still can not say anything, not even one word.
