What does tendinous mean?
Tendinous is an adjective describing something composed of, resembling, or connected with tendons. Tendons are strong bands of dense connective tissue that attach muscles to bones and transmit force, so tendinous tissue is notably tough and fibrous. The word appears most often in medical and anatomical contexts, as in references to tendinous tissue, injuries, or attachments, but it can also characterize meat that is lean and sinewy. Its association with anatomy gives it a technical, somewhat formal tone, although dictionary writers also use it in literary descriptions of physical toughness or texture. Tendinous is related etymologically to tendon and to the broader family of English words connected with the Latin root meaning “to stretch,” including tend and tension. Learning the word is useful for understanding technical descriptions of muscles, joints, and connective tissue, as well as for appreciating the precise vocabulary used in culinary writing.

Where does tendinous come from?
Tendinous comes through Medieval Latin tendinosus, meaning “of or like a tendon,” from Latin tendo, “tendon.” The Latin stem is associated with tendere, “to stretch,” which also underlies English words such as tend and tension. Tendon and tend are therefore cognates sharing the same Latin and Indo-European heritage.
