Correct spelling for the English word "balcom" is [bˈalkɒm], [bˈalkɒm], [b_ˈa_l_k_ɒ_m] (IPA phonetic alphabet).
I apologize, but "balcom" is not a recognized word in the English language, and therefore, an exact dictionary definition cannot be provided. It is possible that you may have misspelled the word or it could be a term specific to a certain field or region.
However, if you meant to type "balcony," then here is a dictionary definition for that word:
Balcony (noun): A platform or external extension that is typically attached to the side of a building, usually above the ground floor and with access from an upper story. It is typically enclosed by a railing or balustrade and is used for various purposes such as providing outdoor space, offering scenic views, or allowing for recreation, relaxation, or social gatherings.
A balcony is commonly found in residential buildings, hotels, theaters, and other structures where such an architectural feature is incorporated. It often serves as an appealing addition to a building, providing an elevated space for occupants to enjoy fresh air, sunlight, or panoramic views. Balconies can vary in size, design, and materials used, ranging from small platforms to expansive terraces. They can be found in urban or rural areas, giving individuals an alternative space to engage with the surrounding environment, observe street activity, or simply enjoy a quiet moment outdoors.
