What does sinker mean?
A sinker is most commonly a small weight attached to a fishing line so that the line and bait sink into the water. Its exact size and material vary with the type of fishing, but traditional versions are often made of lead or another dense material. The word can also denote a person or thing that descends or sinks, although that sense is less frequent in everyday use. In fishing contexts, a sinker is distinct from a float or floater, which helps keep the line or tackle at or near the surface. The term is straightforward and useful in descriptions of angling equipment, fishing techniques, and underwater tackle. Its broader metaphorical possibilities are limited, so it is best understood primarily as a practical noun associated with making something sink.
A weight used to make fishing line, bait, or tackle sink in the water.
"She changed the sinker before casting the line near the rocks."
This is the usual modern sense. The material and shape of the sinker depend on the fishing method and the depth being targeted.
A person or thing that sinks or descends into a liquid or other medium.
"The submersible continued downward as a silent sinker beneath the waves."
This sense is less common and is often literary, technical, or context-dependent.
The plural is formed by adding -s.
"The shop sells brightly colored sinkers for fishing."
A sinker does more than make a fishing line descend: it gives the bait the weight and momentum needed to reach the water below.

Where does sinker come from?
The word combines the English verb sink with the suffix -er, which forms nouns denoting an agent, instrument, or object associated with a verb. English sink derives from Old English sincan, meaning “to go under” or “to be submerged,” and is related to forms in other Germanic languages, including German sinken. The compound sense developed naturally: a sinker is a thing that causes or performs sinking, especially in fishing.
How sinker is actually used
