means A choice or action so likely to succeed or go well that choosing it involves almost no risk.

from A straightforward pairing of two old words: 'safe,' from Latin salvus meaning unharmed or whole, and 'bet,' a gambling term of uncertain origin that surfaced in English around the late 1500s, possibly a shortening of 'abet.' Put together, the phrase grew out of actual wagering language — a 'safe bet' was literally a wager considered a sure thing — before it wandered into everyday speech to describe any dependable choice, no dice or cards required.
