The everyday word cloud covers wisps, sheets and tall heaps, while the names for those forms can feel unfamiliar. Use this ten-genus collection for a short reading session that connects a visible sky scene with a complete written label.
Which names and sets will you practise?
The fixed sequence runs from Cirrus through Cirrocumulus, Cirrostratus, Altocumulus, Altostratus, Nimbostratus, Stratocumulus, Stratus and Cumulus to Cumulonimbus. English labels use the Latin genus names. Other languages have their own display names and registered alternatives. Species and supplementary features are not mixed into this ten-genus set as equivalent categories, and a broad everyday term does not automatically answer for several different genera.
The collection contains 10 names in 1 set. The examples below are actual entries from each set rather than the complete lists. Open a set link to inspect its full sequence and choose a manageable amount of vocabulary for your first session.
Read the differences before typing
Cirrocumulus shows fine white grains; Altocumulus has larger patches with gray shading. Compare the thin veil and halo of Cirrostratus with the blue-gray sheet and dim sun of Altostratus. Stratus is relatively uniform, while Stratocumulus has broad lumpy masses. Cumulus has separate heaps; Cumulonimbus develops a tall tower and a fibrous anvil in this example. Halos and anvils are selected cases rather than universal features. These illustrations cannot identify real skies, measure height or predict weather.
Follow the sequence once, then choose a pair such as Cirrocumulus and Altocumulus for closer reading. Note the depicted grain size or layering in your own words, giving your next round a goal beyond finishing faster.
From the first input to a completed round
The current name stays visible beside the picture, so you can read rather than identify an unlabelled object. Look at the complete spelling of Cirrus and check your keyboard before typing. The first input starts the timer; a matching display name or registered alternative advances automatically without Enter.
Edit unfinished text directly in the field. Pressing Enter with an incorrect nonempty answer adds one error and clears that attempt. The result does not count every deleted or replaced letter as a separate error. When a new name appears, read its picture and words instead of repeating the previous answer.
Displayed names and registered alternatives
The complete name displayed in the current language is the most reliable answer. After each arrow below is an example actually accepted for that particular entry. Alternatives vary by name and language: a shortened form working for one prompt does not create a shortening rule for the rest of the set.
Matching normalizes case, spaces and supported punctuation. Latin accents may be omitted, and German ß can be entered as ss. Meaningful words and numbers still need to match. To practise another language, change the page language first and use that page's labels or registered answers instead of assuming an arbitrary translation will work.
- Cirrus → Cirrus clouds / mares' tails
- Cirrocumulus → Cirrocumulus clouds
- Cirrostratus → Cirrostratus clouds
Choose a small goal for your second round
Your next goal can be more specific than speed. Choose a name that made you pause, such as Nimbostratus, read it in full, and retry the same set in the same language. Note whether you used full names or alternatives and whether you changed devices so that the comparison has useful context.
After a completed round, review time, keystrokes per minute, errors and the best record. Best times are stored in this browser separately by topic, set and language. Results are not combined across devices through an account; keep your own dated note of words you reread if you want a longer study record.
Understand what the illustrations cover
Educational sky scenes depict the ten WMO cloud genera. They cannot identify real weather, measure cloud height or provide forecasts. Halos and anvils are selected examples, not features present in every case.
Use these boundaries to treat the illustrations as aids for reading terminology. A correctly typed name records a vocabulary task, not practical competence in identifying or handling the real subject. When you return to a book or class, check that source's definitions and scope to connect the words with their original context.

This guide and its game are available in Korean, English, Japanese, Simplified Chinese, Traditional Chinese, Spanish and German. Change the language menu to read the instructions and names in that language. The game links below retain your current language choice.
