What rules are there on stressing syllables in words with no accents?

Question

I get how to stress words in Spanish when there is an accent mark, but I am sure that there is probably default rules when there are no accent marks.

Answer 1

I think - but someone else correct me if I'm wrong - that the stress falls on the next to the last syllable when the word ends in a vowel or in the consonants "n" or "s". If the word ends in any consonant except "n" or "s" the stress falls on the last syllable.

And of course if there is an accent it falls on the accented syllable.

Answer 2

Revmaf's answer is correct, although there is one more guideline that I know of concerning stress on syllables without accent marks. In adverbs ending in "mente," such as fácilmente, both the accented vowel ("á") and the "mente" parts of the word are stressed. See the "Stress" article under the "Spanish Grammar" section of the "Reference" page for more details, or use the hyperlink below. link text
