Not everything you look up is a single word.
A phrase works differently from a word. An idiom rarely means what its words say. An abbreviation needs to be spelled out. Until now they all came out of the same mold.
So we taught Linguin to read what you asked for first, then build the entry to match. Look up a phrase and you get phrase notes. Look up an idiom and you get what it really means. Look up an abbreviation and you get what it stands for.
Each entry is also checked against the open web as it is written, so definitions, examples, and common mistakes line up with how the word is actually used.
Nothing to do on your side. Lookups are just sharper.
