The term "putting up front" indicates presenting or highlighting something prominently. Antonyms of this phrase include "hiding", "concealing", "minimizing", "obscuring", and "downplaying". When something is hidden or concealed, it is not put up front, and is instead kept from plain view. Minimizing, on the other hand, means reducing something's significance or importance, making it less of a priority. Similarly, obscuring means making something unclear or difficult to see, as opposed to bringing it to the forefront. Finally, downplaying indicates intentionally making something seem less significant or noteworthy, rather than highlighting it prominently.
