To cloak one's intentions

Origin

The word 'cloak' derives from Old French and originally referred to a loose, flowing outer garment. Beyond its function for warmth or protection, a cloak was historically used for disguise and anonymity, allowing one to conceal their identity, their form, or even objects beneath its folds. From this practical use of hiding something from view, the powerful metaphor of 'to cloak' emerged. To 'cloak one's intentions' vividly suggests wrapping one's true aims or desires in a veil of secrecy, much like a spy might pull a heavy fabric around themselves to blend into the shadows, making their true purpose impossible to discern until the opportune moment.
