I always wondered why there are so few attempts to compose accentual-syllabic poetry in Eldarin tongues retaining metre, rhythm and rhymes. Here is my own modest attempt, just finished. I tried a classic Italian sonnet form, which I personally prefer; I wrote a number in my own language before now attempting Sindarin. Sorry for any Salo-isms, Rausch-isms and any other -isms if they happen; hope got it right, feel free to discuss and propose any corrections :) Anyway, my experiment with 'Elenion Ancalima':

In Elin *rongail, ai Aerennil *mellen!
An Edain *lennen ech or Ennorath;
Ech cirion min Aeryn Annui veren,
I vaethor meleg, *úlomui dan gwath.

Ir ú-verthaster brennyn rim a thelyn,
Nan Golovir aphódiel i rath,
Nelennil *Galgair, onel hiniath
O phen-estel *adadhren ah edhellen!

Hîl *todwaith eglain, hain aderthiel,
Nadh Rodyn *ethul, erui túliel,
Trî 'welwen ivrin erias na Menel;

Minuial ah aduial arnad dîn,
Idh reniar, egleriam Aerennil,
An Amrûn ammen *colel galad în.

*rongail "brightest, exceedingly bright": intensifying prefix ro-, raw- (PE17)+gail
*mellen "beloved": PPP of mel-, cf. hollen
*lennen: PPP of *lenna- "send" as assumed cognate of Q. lenta- as from LEN (it seems Tolkien conceived it different root from DEL in lelya-)
*úlomui "tireless": ú+lom+ui
nelennil: 2 sg. formal (Noldorin inflection assumed, for Earendil "cult" is more expected in Western-oriented society) pt. of neledh- [cf. neledhi gar]
*Calgair: presumed cognate of Q. Calacirya as from KAL+KIR, double-affected
o: following Thorsten Renk, a set of special mutations as for a 'and' assumed
*adadhren "Mannish": on-the-spot construction adan+ren to mirror edhel-len
*todwaith "two people": assumed as a loose compound for metric purpose
*ethul: 3 sg. pt. of *ethol- "came forth"; cf. attested Q. ettul-
*colel :pres. AP of *col- "carry, bring"; cf. Q. *col- < cormacolindor.
