không có gai
/ˈspaɪnləs//ˈspaɪnləs/"Spineless" originates from the literal lack of a backbone, or spine, in invertebrates. This physical characteristic was metaphorically applied to people lacking courage or fortitude. The word first appeared in the 15th century, with the earliest recorded usage in 1485. Over time, the term expanded to encompass a broader range of weaknesses, including lack of character, resolve, and a tendency to avoid confrontation. It now describes anyone who lacks the moral backbone to stand up for what they believe in.
