The French word for linden, tilleul, comes from the Greek “tilos” which describes the phloem of the plant, the fiber which is extracted from the linden bark. Long before humans knew how to extract the fibers from linen or hemp, they knew how to extract linden fibers. Since prehistoric times the linden has been known as the “rope tree”.
In Latin it is called Tilia (and tilio in the Middle Ages)
TiL is the name of the linden in old French, and the root “til” gave rise to many village and place names.
Tils are the ropes made from lindens, because the fibers are long and very strong.
The linden is the “tree that binds” in all senses of the word, TiL is aptly named…
