Morphology
apodeictic = deictic (opaque) = apo + deict + ic
Although 'apodeictic' can be parsed as 'apo-' + 'deictic', knowing 'deictic' does not help a typical learner infer the specialized meaning 'necessarily true, demonstrable'.
Etymology
The word apodeictic comes from the Greek parts apo- 'from' and deiknymi 'to show', so it originally means 'clearly shown'. So, an apodeictic statement is one that is shown so clearly that it cannot be doubted.
