exhibitionist

The word 'exhibitionist' is a modern formation, built upon the older noun 'exhibition'. Its core, 'exhibit', originates from the Latin verb exhibere, meaning 'to hold out, present, show', itself composed of ex- ('out') and habere ('to hold'). The suffix -ion transforms the action into a noun ('the act of showing'), and the agent suffix -ist specifies a person who performs that act. While the general sense of 'one who shows off' appeared in the 19th century, the specific clinical term for a psychosexual disorder emerged in the 1890s, illustrating how a classical root evolved to describe a very specific modern behavior.

Structure: exhibit (show) + ion (noun suffix) + ist (person who does) exhibit: from Latin exhibere (to hold forth, present, show), a verb-forming element. ion: from Latin -ionem, a suffix forming nouns of action or state. ist: from Latin -ista, from Greek -istēs, a suffix denoting a person who practices or is concerned with something.
