Capable of being contemplated, observed, or thought about carefully; worthy of consideration.
From contemplate plus -able (capable of being). The -able suffix transforms the verb into an adjective meaning 'able to be contemplated.'
This word is technically grammatical but extremely rare because 'contemplatable' sounds awkward and philosophers prefer saying something 'is fit for contemplation' instead—it shows how not all grammatically possible words survive in actual usage.
