Here's why:
* Abridged dictionaries are shorter, more concise versions of larger dictionaries. They typically focus on common words and provide basic definitions.
* The OED is the most comprehensive dictionary of the English language. It contains a vast collection of words, including historical usage, etymology, and multiple definitions. It's considered the gold standard for lexicographers and language enthusiasts.
Therefore, the OED is far from abridged. It is a massive and detailed dictionary.
