However and how ever- some more examples

I am going to disagree with both Tony and Rahul. "However" and "How ever" are not fully synonyms, at least according to my two large desk dictionaries -- Merriam-Webster Collegiate and American Heritage.

Tony gives a proper description of "however" as a conjunctive adverb. But "how ever" as two words cannot be used as a conjunction. Both dictionaries consider "how ever" to be an alternate (and somewhat archaic) spelling of the adverb form.

Thus you can say "How ever you slice it, it's still sliced bread" but not "How ever, I disagree." On the other hand, you can say "However you slice it, it's still sliced bread" and "However, I disagree."

They are identical in meaning and can be exchanged freely.

She told me I could eat it how ever I wanted to. However, I did not want to eat it at all.

She told me I could eat it however I wanted to. How ever, I did not want to eat it at all.

However is a 'conjuntive adverb'

As an adverb:

    -In whatever manner. "Do it however you want."

    -To whatever extent. "However far he may get, there'll be many that get further."

An a conjunction:

    -It is used in the same way as 'although,' 'though,' 'but,' and 'yet.'

That's only a short answer on 'however'.....however, it can be used in several ways.

I agree with Tony that it can be used as synonym of 'but'.

Dictionaries can be very helpful in such matters.
