Gosha – an angle, a corner, privacy
Given below is a couplet by Shahzad Ahmad which brings out the meaning of the word beautifully.
gosha-e-dil ki khamoshi ka tamannaii main
aur hangamay utha Laya hai bazaar se tuh.
My desire was to keep it silent in the corner of my heart,
and you have brought an uproar with you from the market.
