Morphology

The noun is a substantive use of the adjective 'observable', but the computer-science sense is specialized and not fully predictable from the base meaning.

Etymology

Observable comes from the verb observe, which means 'to watch'. In programming an observable is a thing you 'watch' for new values or events, so other code can get updates when something changes.
