Visceral English words

I often hear that other languages like Russian, Romanian, French, etc, have words that are more "powerful" or evoke more feelings than English ones. Example: "war" doesn't sound that bad, really, but in Romanian, "razboi" with a hard rolled r and an accent on the 2nd syllable sounds more powerful.

What are some English words that are evocative?

After re-reading this question, I think what you're really after is the concept of sound symbolism. On Google Books, you'll find a reasonably complete copy of a book entitled Sound Symbolism, a good read on the theory in general. It's pretty dense, but has a lot of good information.

As for a list of English words, I found it difficult to come up with a satisfactory list of "powerful" words, so here instead are the 70 most beautiful words in English as determined by a poll over 40000 native and non-native speakers, carried out by the British Council in 2004.

Hope this helps!
