A former support or resistance zone that failed and is then retested from the other side, expected to act with the opposite polarity.
In market-structure vocabulary, a breaker is the candle zone that held price before a level broke, revisited after the break. A support area that failed becomes a candidate resistance area on the retest, which is the same idea as the polarity-principle dressed in newer language.
It is closely related to order-block but describes a level that has already been violated, rather than one that produced the original move. The practical use is identical: a defined zone for an entry with a nearby invalidation.
The honest assessment is that breaker blocks are one of many labels for a retest, and that the label carries no independent evidence. The value, if there is any, lies in having a precise zone and therefore a small stop, not in the name.

Support, resistance and the flip. Support is a price where buyers keep stepping in and the fall stops; resistance is a price where sellers keep stepping in and the rise stops. Once price closes above an old ceiling, that same level often acts as the new floor.Breakout and retest. Price stalls under the same level several times, pushes above it, then drops back to touch it from above before carrying on. That touch is the retest, where the old ceiling is tried as a floor. A break that falls straight back under it is a false breakout.
