Combine a purpose with a useful characteristic
“A container for water” is broad. Adding portable use, double walls, and keeping drinks hot or cold makes the intended object clearer. These are complementary clues, not a reason to make every prompt longer.
The lines below preserve the actual English query and response. Chinese and English workflows were recorded separately, so their candidate lists may differ.

Treat candidates as things to check
The English demonstration suggests “保温杯,thermos.” The Chinese query additionally returns a broader container term and a functional expression. These are not all interchangeable object names.
Ask whether you need the name of an object or a phrase describing its function. Add details if you need a material, structure or specialist term. This is editorial guidance, not additional output attributed to the model.
Open the card and return to the description
The demonstrated thermos card describes a bottle that keeps drinks hot or cold. Compare that meaning with the characteristics that mattered in your original question.
If a picture, definition or example does not fit, stop and verify it. Refine the description or use another reliable reference. AI candidates do not replace specialist terminology checks.
A description structure you can reuse
Give a situation, a purpose and one visible or structural feature. You can rule out an alternative, but avoid presenting uncertain guesses as facts.
- Context: where would I encounter it?
- Purpose: what is it used for?
- Feature: what does it look like or how is it built?
- Check: does the candidate fit those clues?
Questions before you begin
Why do the English and Chinese lists differ?
Different wording and languages can produce different candidates. A longer list is not evidence of greater accuracy; check the actual meanings.
Does reverse dictionary mean sorting words by their endings?
Here it means finding a word from its meaning or description. This is a different use of the term from a dictionary arranged by word endings.
