A synonym for “frontstage” could be “foreground”.
The term “frontstage” often refers to the area that is in the forefront or most visible part of a performance or event. Similarly, “foreground” implies being in the most prominent or immediate position. For example, “The actors on the frontstage captured the audience’s attention.” can be rephrased as “The actors in the foreground captured the audience’s attention.” In both cases, the focus is on the part that is most visible and central to the viewer’s experience.
Another possible synonym is “limelight”. This word is often associated with being in the spotlight or at the center of attention. Just as “frontstage” implies a place of prominence, “limelight” suggests being in a position where one is highly visible and the focus of attention. For instance, “She loves being in the frontstage of the fashion industry.” can be expressed as “She loves being in the limelight of the fashion industry.”
“center stage” is also a fitting synonym. It literally means being in the middle and most important part of a stage. This is similar to “frontstage” in that it indicates a position of prominence. For example, “The singer took the frontstage during the concert.” can be rewritten as “The singer took center stage during the concert.”
