dépoétiser

A literary verb meaning to strip something of its poetic or idealized character — a critic might say tourism a dépoétisé un lieu autrefois romantique (has stripped a once-romantic place of its poetry). Rare outside literary and critical writing.

• La publicité a fini par dépoétiser ce paysage autrefois sauvage. — Advertising eventually stripped this once-wild landscape of its poetry.
• Certains critiques trouvent que la traduction dépoétise le texte original. — Some critics feel the translation strips the original text of its poetry.
• Le tourisme de masse a dépoétisé la petite île. — Mass tourism has stripped the small island of its poetic charm.

A rare, literary verb — most French speakers would never use it in conversation and would instead describe something as banal or dénaturé (spoiled/distorted) rather than reach for dépoétiser.
