adjective 'shabby' is used to describe something of poor quality or appearance that has been neglected. This typically applies to clothing, furniture, and houses that are worn and tattered. In a more figurative sense, 'shabby' can also be used to refer to something that is not respected or valued, such as old-fashioned ideas and expectations.
This room has shabby furniture.
My friend wears shabby clothes.
it is important to note that the adjective 'shabby' is usually reserved for inanimate objects, as opposed to people. For example, rather than saying 'The shabby man,' one would say 'The shabbily-dressed man.'
