The word "releasing" suggests the act of making something available for use or circulation, but its antonyms convey the opposite meaning. One of the most fitting antonyms for re-leasing is "retracting," which means to withdraw, pull back, or take back. Conversely, "withholding" describes the retention of something and refusing to release it. Another antonym is "holding," which alludes to the act of keeping something within one's possession, control, or confinement. Similarly, "denying" implies the refusal to release what is being requested, while "refusing" suggests a deliberate decision to withhold something. These antonyms reflect the concept of the opposite of releasing and provide a range of alternatives for various contexts.
