False. Here's what I asked ChatGPT just now:

What criteria do dictionaries use to decide which definitions for words are put in as entries?

Here's ChatGPT's response:

Good question! Dictionaries don’t just throw in every possible meaning of a word—they follow careful criteria, and the exact process depends on whether it’s a general-use dictionary (like
Merriam-Webster or
Oxford English Dictionary) or a specialized one. The main criteria are:
1. Evidence of Use (Attestation)
- Lexicographers look at corpus evidence (large databases of real-world texts) to see if a word or meaning is actually used by many speakers or writers.
- A new definition usually needs to appear in multiple independent sources over time, not just in one-off cases.
2. Frequency
- If a meaning shows up often enough in print, online, and spoken usage, it’s more likely to be included. Rare or fleeting uses usually don’t make it in.
3. Breadth of Use
- A definition has to be recognized by a wide enough group of people, not just a single community, unless the dictionary is specialized (like legal or medical dictionaries).
4. Longevity / Staying Power
- Dictionaries don’t want to chase every passing slang trend. They look for persistence: does the usage stick around, or does it vanish after a season?
5. Clear Meaning
- The meaning has to be distinct enough from other senses of the word. If it’s just a tiny nuance, lexicographers may fold it into an existing definition instead of giving it its own entry.
6. Documented Sources
- Traditionally, dictionaries relied on published books, newspapers, and academic texts. Today, they also track social media, blogs, TV transcripts, and other digital sources, but still require verifiable, recordable use.
So in short:
a definition gets in if it’s repeatedly attested, broadly and clearly used, and durable enough to matter to readers.

Do you want me to give you an example of how a dictionary added a
new sense of an existing word (like
mouse → computer device) and how they justified it?
