Here's an old post where I explain primary stress. It's a bit windy but maybe examples help get the point across. It's not as complicated as it sometimes looks!
____________________
Hello! According to Appendix E, the primary stress of these names should be:
g
Aladhon (note that
Sindarin -dh- is considered a single consonant, represented in
Elvish writing with a single letter, as in this version:
gAlaðon)
Start with the penultimate syllable, or "the last syllable but one", as
Tolkien puts it in Appendix E. Here, this syllable contains a short vowel (a), not a diphthong, and the short vowel is not followed by two or more consonants. Thus the primary stress moves to the left of the penultimate syllable (in this case the first syllable). Compare l
Egolas.
cel
Ebrant
Here, the last syllable but one contains a vowel that is followed by two consonants. This syllable is thus stressed.
n
Iphredil
Same description as for Galadhon. To say it a different way, if the penultimate syllable here contained a long vowel, a diphthong, or the short e was followed by two or more consonants, the penultimate syllable itself would be stressed. But none of these things apply in this example, so again the primary stress moves to the syllable to the left.
Sindarin
th, ch, dh, are
single consonants (and again, written with single letters in Elvish writing), that's why it's d
Enethor, not
denEthor, using Tolkien's own example in Appendix E.
