What does plugging mean?
Plugging most commonly refers to inserting a plug or connecting equipment so that it receives power, data, or sound. The expression "plugging away at" something describes working on it patiently and persistently, often over a substantial period. In broader figurative use, plugging means filling a gap, correcting a shortcoming, or preventing something from leaking: a policy may plug a funding gap, for example. In informal American English, plugging can also mean promoting a product or person, while in slang it can refer to firing a bullet. These meanings are connected by the word's practical image: a plug closes or completes a connection where one is needed. The verb is often used in the gerund-participial form "plugging," and phrases such as "plugging in" and "plugging gaps" are especially common.
