'publicizable' originates from English, specifically from the verb 'publicize' (public + -ize), where 'public' comes from Latin 'publicus' meaning 'of the people', '-ize' meant 'to make', and the suffix '-able' means 'capable of'.

'publicize' was formed in English by adding the verb-forming suffix '-ize' to 'public' (from Latin 'publicus'); later the adjective 'publicizable' developed by adding the adjective-forming suffix '-able' to 'publicize'.

Initially the elements meant 'to make public' (public + -ize) and 'capable of' (-able); over time these combined to give the current meaning 'able to be made public' (the meaning has remained largely consistent).
