In a way that is done poorly or in a careless manner.
The room was decorated shabbily, with peeling paint and old furniture.
Shabbily → The word is derived from 'shabby' (from Middle English *shabbe*, meaning worn out or ragged) and the suffix '-ly' (meaning in a manner of). Thus, 'shabbily' means in a manner that is worn out or ragged.
Think of something that looks 'worn out' ('shabby') and how it is done 'in a manner' ('-ly'). This helps you remember that 'shabbily' describes something done in a worn-out way.
