How Observational
Surface Forms
Morphology
observational = observation (transparent) = observe + ation + al
The adjective is formed in the regular way from 'observation' plus '-al', and its meaning is straightforwardly 'relating to observation'.
Etymology
Observational comes from the verb observe, which in turn comes from Latin observare meaning 'to watch' or 'to look at carefully'. So observational describes something based on watching or real facts, not just on ideas or theory.
