Whichever, however, whatever

[ROBINDESBOIS]

These conjunctions introduce conditions which always seem to obtain and cannot seem to be changed.
Can anybody explain to me the meaning of this definition, or can you paraphrase it?

[poli]

Whatever and whichever are like cualquiera en Spanish.

How ever can mean cómo but with more urgencey. Example: How ever will they solve that problem in the Gulf of Mexico.

However means something between but and nevertheless. (pero y no obstante)

[wafflestomp]

However is a synonym of "but" or "pero".

I would go to the store, however, my car is broken.

[CrOtALiTo]

Then Poli.

How ever means como but in a situation more urgent.

I can use the phrase in the following instances.

Please don't hesitate to correct me.

How ever you most fix my car right now, because I need to have my car this afternoon.

Here you can see that it's more seems of a command than a suggestion.

I will be grateful for your support.

Then Poli.

How ever means como but in a situation more urgent.:good: Correct.

I can use the phrase in the following instances.

Please don't hesitate to correct me.

How ever will you fix my car right now?, because I need to have my car this afternoon. Adding will makes it correct, but it really doesn't sound right to me. I rewrote it below.

How ever will my car be fixed by this afternoon? I need it by then!

Here you can see that it's more of a command than a suggestion.

I will be grateful for your support.

There you go Croalito, I rewrote it a little more naturally above in green.

[CrOtALiTo]

Thank you for the corrections.

Yes perhaps I need to write more nature.
You rewrote my example and well they seems like.
