Answer:
The word "chamber" means a room.
Explanation:
William Shakespeare's comedy play "A Midsummer Night's Dream" revolves around the comic love o the numerous characters with the upcoming wedding of Theseus and Hippolyta as the backdrop for the love theme. With the numerous characters intertwined in their love affections, the play focused on how people perceive love to be something that is only about physical appearance and not care much about the emotional value/ aspect.
The given dialogue of Quince in Act III scene i of the play reveals the problem of bringing "moonlight" in a room. With the plan to perform the love story of Pyramus and Thisby for the newly wed couple Theseus and Hippolyta, the performers were going through the particulars that they had to take care of for their performance. And since the play will be presented in an enclosed room and not the outside, they had to make certain changes to it. Like, a real lion in the scene which will be replaced by a person providing a prologue where he declares the lion isn't a real lion. Likewise, considering Pyramus and Thisby met at night, under the moonlight, and with a wall in between them, it is only natural to try to replicate the scene in however much they can manage. For that, they had to find ways to make it seem reasonable, with a man acting as the wall while someone holds a lantern and a bush.
Thus, when Quince mentions that "to bring the moonlight into a chamber" is a hard thing, he is talking about how to bring "moonlight" inside a room.
