TOL ERESSEA: Here, a biblical fellow returns, to meet an archaic palindrome and a sibilant ocean.
HALBARAD: Half German article and liquid marketing. For him.
ERECH: Place of mirth ... but it's not unmixed.
RADBUG: Brag - dubiously, at first, you hear - before chaos ensues to expose him.
EAGLES: Seasoned sailors have more than one of these. But be that as it may, it's mangled to reveal these majestic creatures!
TEARS: Not all of these are evil.
UMBAR: Does one hesitate to suggest a pub here?
ROSE: She's inflamed - and troubled.
NUPTIALS: One must dress, groom, prepare? - put nails in order, certainly - for them.
OSGILIATH: Is David's foe around here?
FORLONG: Beat a Weasley? He's there - but discombobulated.
TOOKS: Group of sheaves slightly disturbed by - or rather for - the first ones to kill.
HAVENS: They're beardless and bewildered.
ELANOR: A role reversed; an article swallowed; a girl revealed.
KNIGHTS: Merry and Pippin, in white satin? (For thus it sounds, in song).
IORLAS: A painter's choice - Rembrandt's, initially - and Goya's, finally - mingles to reveal him.
NAZGUL: See this fearsome thing return, endlessly crazy, to endlessly deceive.
GILDOR: Aged apparatus collapses to reveal him.
Who said they all have to be Tolkien words? Nuptials/weddings feature in Tolkien's *story.* I like to make things a little different sometimes. We've had passwords about food and drink in the books, and Tolkien didn't invent tea and coffee! And the same goes for 'Tears,' (clue 6).
I'm pretty sure Eomer and Lothiriel's wedding is only in the Appendices, along with Merry's and Pippin's.
Over to you!
