The term 'truncated words' refers to words that have been shortened by removing one or more of their letters. This is often done to create acronyms or abbreviations, such as 'NATO' for North Atlantic Treaty Organization. Truncated words can also be used to create slang terms, such as 'BAE' for 'BABE'. In crossword puzzles, truncated words are often used as clues, with the full word being the solution. The five-letter abbreviation for truncated words is 'ABBRS'.
