Etymology: "Tissued" is simply "tissue" with the "-ed" ending added, so it describes something that has tissue or is made of tissue. The word "tissue" itself comes from Old French "tissu," the past participle of "tistre," meaning "to weave," which is also the ancestor of the English word "text." That shared root is a useful reminder that a tissue, whether a cloth or a biological structure, is something woven together. The biological sense of "tissue" grew out of the textile sense. Anatomists borrowed the word because the fibers and cells of an organism seemed to be interlaced into a fabric, much as threads form a cloth. "Tissued" follows the same pattern as other adjectives built from nouns with "-ed," so its meaning is easy to work out from its parts.
