"Si no sabe ni aparcar" --> " He does not even know how to park (the car)" Some examples with the structure: "Dices que se te da bien la informática? Si no sabes ni encender el ordenador!" --> You say that you are good with computers? You don't even know how to turn it on. "No creo que seas muy mayor. Si no tienes ni barba." --> I don't think you're too old. You don't even have a beard. The second one is mysterious to me because I don't understand the sentence ("ma" is not a spanish word so I'm trying to figure out what the intention of the sentence is, but with for instance "me" it does not say me anything either). So... focusing only on the "te taparé la boca" part, its translation could be "I'll cover your mouth" or "I'll seal your mouth". Actually without context it could range from as soft as "cover" to as hard as "seal", because "tapar" is a very generic word, I'd say the context means everything here, although the basic meaning is that of covering/shutting. However "tapar" always implies using something over the thing you're "tapando" (that's why I chose "cover" as the first translation), although the best word for "cover" in spanish is "cubrir", which is generally speaking softer than "tapar. Thinking about it I would say that a good explanation of "tapar" would be "to cover up to the point to force it to be closed".

Hello Valeriya, here is the literal translation of the text you just submited: 1) - Father drives much better than mother. - I don't think he drives better. He doesn't even know how to park... - Shut up! it's better he doesn't hear you saying that... When someone says "Si no sabe ni aparcar" it means the person doesn't have the ability of driving well and he is not able to park his car. 2) I will cover your mouth so you don't call her. "Tapar" is to cover something up, "tapar la boca" is to cover the mouth so the person can't talk anymore.

"Si no sabe ni aparcar" = "он даже не умеет парковаться!" "Te taparé" = "заткну, закрою". I could give you some examples, but I think it is better to let the native speakers to do it :)
