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.
- Learner
- What is a double-walled bottle that keeps drinks hot or cold when I go out called?
- Bear
- Here are some matching words. 保温杯，thermos.
- Bear
- thermos. a bottle that keeps drinks hot or cold.
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?
Add one useful constraint when a candidate is too broad
The recording includes both an object name and a functional expression. If you need the object, add a constraint such as “I need the name of the container, not its heat-retaining function; it has double walls.” This is an editorial prompt to try, not a second query or a promise about the next result.
The external English entry describes thermos as a vacuum-insulated vessel and notes its origin in the Thermos trademark. Check the structure and local usage when precision matters; a candidate word is not a product-brand recommendation.

Check a new input mode on its own terms
This page demonstrates one description-to-candidate workflow. Identifying a photographed object, reading text from an image, transcribing speech and interpreting a typed description use different clues; this example does not show that they perform identically.
For an image, check that the intended object is visible. For voice, check whether the transcription keeps your meaning. In text, separate facts from guesses. Check the current app for available inputs, waiting and usage costs.

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.
