BUNGO: Underground? Overground? Womble, that's he.
DAUR: Medical chap swallows half a Vala for him.
3. Deity overlaps short palindrome girl to meet perturbed footwear? A bigger girl emerges.
MERRY: Mouse changes heads to reveal him?
5. Hard word. Starts with clear direction to a pub. But why, I say? To finish it off with a dwarvish tool.
ADALGRIM'S AUNT: Palindrome girl leads the way to a teacup omen - he's there, but the whole answer is one of his female relatives.
7. One solitary girl? It's revolutionary.
PRIMROSE: Not poetry, but it contains edge - and then she appears.
9. His posterior leapfrogs and is disorientated, but meets a headless 80s singer.
It's in LOTR itself.
'Long live the Halflings! Praise them with great praise!
Cuio i Pheriain anann! Aglar'ni Pheriannath!
Praise them with great praise, Frodo and Samwise!
Daur a Berhael, Conin en Annun! Eglerio!
Praise them!
Eglerio!
A laita te, laita te! Andave laituvalmet!
Praise them!
Cormacolindor, a laita tarienna!
Praise them! The Ring-bearers, praise them with great praise!'
Mind you, I once thought 'Conin en Annun' meant 'Frodo and Sam.'
