Fimbrethil was Treebeard's long-lost wife.
The pair loved each other before even Morgoth first arose in power during the youth of the world. Translated, her name meant, according to the 1966 Index, 'slim-birch' (according to Appendix F, 'slender-beech').
As with all of the other Entwives, Fimbrethil had been missing since Sauron's forces destroyed the gardens of the Entwives during the Second Age. At the time of the War of the Ring, Treebeard had not seen his beloved Fimbrethil for over 3,000 years.
Treebeard said that the Ents made no great songs about the lost Entwives; they were content to chant their beautiful names under their breath whenever their thoughts turned back to them.
During the Last March of the Ents against Isengard, Treebeard felt that many of the Ents were marching to their doom, and that he might never see his Fimbrethil ever again. Treebeard told Merry and Pippin that Saruman had to be stopped, although he would dearly have liked to see Fimbrethil once again.
