The word "binder" originates from the Old English verb bindan ("to tie or fasten"), which has Germanic roots. The suffix -er is an agentive suffix in English, used to form nouns indicating a person or thing that performs an action. Thus, "binder" literally means "one who/that which binds." Over time, its usage expanded from literal binding (e.g., bookbinding) to metaphorical or technical contexts (e.g., data binding in computing).
