Meaning
To take a personal risk by expressing an uncertain opinion, making a bold prediction, or publicly supporting someone when others may disagree. The phrase often suggests that the speaker could be proved wrong, criticized, or left without support. It is especially common in the formula “I’ll go out on a limb and say…” when introducing a tentative but confident guess.
Origin
The limb is a branch of a tree. Moving farther out along a branch leaves a climber in a precarious position: the branch may bend or break, and retreat may be difficult. This physical image became a metaphor for taking an exposed or unsupported position. Figurative examples appeared in American English by the late nineteenth century; an example was printed in the Steubenville Daily Herald in 1895.
