Disconnect is traditionally a verb meaning to sever or interrupt a connection, but in recent years a noun sense has gained prominence. The noun refers to (1) an inability to mentally reconcile two or more things, (2) an inability for two or more parties to agree or to understand each other, or (3), more generally, a disparity or gap. Also, it’s sometimes simply short for disconnection.
The noun disconnect is an early 20th-century development, though it was rare until around 1980. In this century it is inescapable. Why so many 21st-century writers resist the longstanding nouns disconnection and disparity is hard to say. With disconnection, the resistance perhaps relates to that word’s infrastructure-related meanings. Disparity perhaps gives way to disconnect because the latter’s harder sounds better convey disconnectedness. In any case, disconnection and disparity remain perfectly good words from a logical standpoint, and disconnect would often bear replacement with one or the other.
