When someone or something "drags along," they are moving slowly and awkwardly, often as if they don't want to be where they are or do what they're doing. Synonyms for this phrase include "trudges," "plods," "slogs," and "shuffles." These words evoke a sense of effort, reluctance, and heaviness. Other possible synonyms might include "wades," "creeps," "limps," "labors," "moseys," or "dawdles." Each of these words suggests a slightly different nuance or degree of slowness and resistance, but all convey a sense of sluggishness or tedium. As with all synonyms, the key is to use the word that best fits the context and the tone you want to convey.
