bonsaïfier

An informal, fairly recent coinage from bonsaï (the miniature tree) meaning to shrink or miniaturize something, often used figuratively and a little playfully — a shrunken budget, a scaled-down project. Not in most standard dictionaries.

• Le projet a été complètement bonsaïfié faute de budget. — The project got completely scaled down for lack of budget.
• Ils ont bonsaïfié leur ambition initiale. — They shrank their original ambition.
• C'est un néologisme, pas un mot du dictionnaire académique. — It's a neologism, not a word in the academic dictionary.

This is playful, informal coinage, not standard vocabulary — a learner is far more likely to read it in a blog or opinion piece than to need it in ordinary conversation.
