Ben planned on going to the zoo; however, he didn't have a car and therefore, couldn't go.
You would use "however" to show a contrast or contradiction between two ideas in the sentence. For example, "She wanted to go out; however, he preferred to stay in."
You can use the sentence: "May I have your permission to proceed?"
You can use "alter" in a sentence like this: She decided to alter her appearance by cutting her hair short.
The word "vouchsafed" is a verb in the past tense. An example of a sentence using the word would be: It was only last week that he vouchsafed that information.
I would use "jeopardy" in a sentence like this: "Her reckless behavior put her safety in jeopardy."
The reasonableness of conduct is a legal standard used to evaluate if someone acted in a way that an ordinary, prudent person would in similar circumstances. In a sentence, you could say "The court determined that the reasonableness of conduct in this case was questionable due to the lack of care taken by the defendant."
You would be unlikely to use it in a sentence, as it is an extremely obscure word. It is a verb meaning 'cut off', so if you really want to use it you would use it in place of those words. However, in most circumstances it would be seen as inappropriate.
"I defy your denunciation!" shouted the defendant. The denunciation was, however, final.
just like BUT ..
Technically you just used it correctly in a sentence. However if you would like it to retain it's natural meaning a fair example would be as such, "The grave robber excavated the corpse."
I would use it correctly in a sentence, of course. Thank you for asking.
Would not that be "Would not that be?"?
I don't like writing, however, I am good at it.
