The concept of "making an entrance" refers to the act of entering a room or space in a dramatic and attention-grabbing way. However, there are many antonyms to this expression that suggest a more subdued, subtle or uneventful entrance. Some options include "sneaks in," "slips in," "arrives quietly," "enters unnoticed," "appears meekly," "arrives modestly" and "walks in unobtrusively." Such entrances may indicate a desire to keep a low profile or to avoid drawing attention to oneself. Alternatively, they may be appropriate in more formal or solemn settings where ostentatious displays are not appropriate.
