corseter

Corseter literally means to put into a corset, but its modern everyday use is almost always figurative: to constrain something rigidly, leaving no flexibility (un budget corseté par des règles strictes, une réglementation qui corsète l'économie). It's common in economic and political journalism.

• Les nouvelles règles corsètent le budget des collectivités. — The new rules straitjacket local government budgets.
• Elle refuse de se laisser corseter par des conventions rigides. — She refuses to be constrained by rigid conventions.
• Ce carcan administratif corsète les petites entreprises. — This administrative straitjacket constrains small businesses.

In modern French this verb is almost always figurative (to overly constrain), not literal (to physically lace someone into a corset) — a learner translating it literally will sound old-fashioned or confusing.
