At basic level, students often have only 'hot' and 'cold' for temperature. The day was hot. The water was cold. But English has a scale of temperature words from very cold (freezing) to very hot (boiling). Each word covers a different range. 'Cool' is pleasantly cold. 'Cold' is uncomfortably cold. 'Freezing' is dangerously cold. 'Warm' is pleasantly hot. 'Hot' is strongly hot. 'Boiling' is extremely hot. Students who use only 'hot' and 'cold' miss most of the range. They cannot distinguish a pleasant cool morning from an uncomfortably cold one. They cannot describe the difference between warm tea and boiling water. This lesson covers the temperature scale at A2 level. It also addresses the confusion between 'hot' (temperature) and 'spicy' (food with chillies) — a common error covered in lesson #46 but worth mentioning again.
Before you start — think honestly about your own teaching and experience.
Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.
VERY COLD: freezing — It is freezing outside this morning.
COLD: cold — The water in the river is cold.
COOL: cool — A cool breeze made the afternoon pleasant.
MILD / WARM: mild — The weather is mild today, not too hot or cold.
WARM: warm — The blanket is nice and warm.
HOT: hot — Be careful — the soup is hot.
VERY HOT: boiling — The water is boiling on the stove.
Look at the scale. Why does English need so many temperature words? When does the difference matter?
Each word covers a different range of temperature, and the difference matters in real life. 'Freezing' suggests very low temperature — possibly dangerous, certainly uncomfortable. 'Cold' is uncomfortable but not extreme. 'Cool' is pleasantly cold — refreshing. 'Mild' is moderate, neither hot nor cold. 'Warm' is pleasantly hot — comforting. 'Hot' is strongly hot — possibly uncomfortable. 'Boiling' is extreme heat — possibly dangerous. A student who says 'the tea is hot' might mean 'too hot to drink' or might mean 'pleasantly warm'. The listener cannot know without more context. Saying 'the tea is warm' (drinkable) or 'the tea is boiling' (too hot to drink) is much clearer. Students who know the full scale can describe temperatures precisely.
A: A summer afternoon, the sun is strong, you cannot stay outside for long: It is ________ today.
B: A spring morning, the sun is warming the air, comfortable to walk: It is ________ today.
C: A winter morning, ice on the windows, you can see your breath: It is ________ today.
D: An autumn evening, slightly cool, you might want a light jacket: It is ________ today.
Which word fits each: hot / boiling / warm / mild / cool / cold / freezing?
Each context fits a specific word. Context A (cannot stay outside): 'hot' or even 'boiling' if extreme — strong heat. Context B (sun warming, comfortable): 'warm' — pleasantly hot. Context C (ice on windows, breath visible): 'freezing' — very cold, possibly with frost. 'Cold' is also possible but freezing captures the extreme. Context D (slightly cool, light jacket): 'cool' or 'mild' or 'chilly' — pleasantly cold or moderate. The choice depends on how cold it actually is. Students should match the word to the actual temperature, not default to hot or cold.
The soup is hot — I burned my tongue. (= high temperature)
The soup is hot — it has lots of chillies. (= spicy)
In temperature contexts, 'hot' means high temperature. In food contexts with strong spices, 'hot' can mean spicy. The two meanings sometimes confuse students. How can we tell which one is meant?
'Hot' has two common meanings in English. The temperature meaning (high temperature, like fire or boiling water) is the original. The spicy meaning (full of chillies, mouth-burning food) is a secondary use that comes from the burning sensation chillies cause. Native speakers use context to tell which is meant. 'The weather is hot' (temperature). 'The curry is hot' (could be either, but often spicy). 'The tea is hot — I just made it' (temperature). 'The chilli sauce is hot' (spicy). To avoid confusion, students should use 'spicy' for the chilli meaning when possible. 'The curry is spicy' is clear; 'the curry is hot' is ambiguous. For temperature, 'hot' is the right word in most contexts. The food adjectives lesson (#46) covers this in more detail.
| Word | Approximate temperature | How it feels | Typical use |
|---|---|---|---|
| freezing | Very cold (often around 0°C or below) | Painfully cold, uncomfortable | Winter mornings, ice forming, dangerous cold. |
| cold | Cold (5-15°C) | Uncomfortable, you need warm clothes | Cold weather, cold drinks, cold food. |
| chilly | Slightly cold (15-18°C) | A bit cold, not too uncomfortable | Cool mornings, slight cold, casual. |
| cool | Pleasantly cold (15-22°C) | Refreshing, pleasant | Cool breeze, cool drinks, pleasant cold. |
| mild | Moderate (15-22°C) | Neither hot nor cold | Mild weather, mild winter, moderate. |
| warm | Pleasantly hot (22-28°C) | Comfortable, cosy | Warm weather, warm bed, warm welcome. |
| hot | Hot (28-40°C) | Uncomfortable for many people | Hot summer, hot food, hot drinks. (Note: also = spicy with chillies) |
| boiling | Very hot (above 40°C, or actual boiling water 100°C) | Extremely hot, dangerous | Heatwave, boiling water, very hot food. |
DISTINCTION 1 — Cold vs cool: Both are below comfortable temperature, but cool is pleasant and cold is uncomfortable. A cool drink on a hot day is refreshing. A cold drink might be too cold to enjoy. 'Cool weather' suggests pleasantness; 'cold weather' suggests discomfort. Choose based on whether the cold is wanted or unwanted.
DISTINCTION 2 — Warm vs hot: Both are above comfortable temperature, but warm is pleasant and hot is uncomfortable. A warm bath is relaxing. A hot bath might be too hot. 'Warm weather' suggests comfort; 'hot weather' suggests discomfort or strength. Warm welcome is friendly; hot welcome is unusual.
DISTINCTION 3 — Freezing and boiling are extremes: Both are casual everyday words for the extremes. 'It is freezing!' (informal but common) means very cold. 'The water is boiling!' (about water actually boiling, but also 'I am boiling' for very hot). Use these for emphasis or actual extreme conditions.
DISTINCTION 4 — Hot has two meanings: 'Hot' for temperature (the soup is hot — careful) is the basic meaning. 'Hot' for food with chillies (the sauce is hot — full of pepper) is a secondary meaning that confuses students. For chilli food, use 'spicy' to be clear. Save 'hot' for temperature.
DISTINCTION 5 — Mild and chilly are useful additions: 'Mild' suggests moderate temperature, neither hot nor cold — useful for describing pleasant weather. 'Chilly' is casual for slightly cold — less serious than 'cold'. Both add range to students' descriptions of weather and conditions.
Temperature words come up constantly in everyday conversation — talking about weather, food, drinks, environments. Students who know only 'hot' and 'cold' miss the precision needed for natural conversation. The scale gives them tools to describe pleasant vs uncomfortable temperatures clearly. Cultural context matters: what counts as 'hot' or 'cold' varies by climate. A morning that feels mild in one country might feel cold in another. Students should learn the words and apply them based on their own experience. The temperature words also extend metaphorically — a 'warm welcome' (friendly), a 'cold reception' (unfriendly), a 'cool head' (calm thinking). These metaphorical uses come naturally once the literal meanings are clear.
Use real or remembered weather to teach temperature words. Ask students to describe today's weather, yesterday's weather, last week's weather. Ask about hot food, cold drinks, mild evenings. Real situations with their own temperatures fix the words in memory. Avoid abstract teaching — temperature words live in real-life experience.
Choose the best temperature word for each situation. Think about how hot or cold the situation actually is.
Each sentence has a problem with a temperature word — wrong choice, contradiction, or wrong intensity. Suggest a better version and explain.
Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.
STEP 1 — The temperature scale (5 min): Draw a horizontal line on the board. Mark VERY COLD on the left and VERY HOT on the right. Place the words: freezing, cold, cool, mild, warm, hot, boiling. Discuss each. Establish that English has a clear scale of temperature words.
STEP 2 — Pleasant vs uncomfortable (6 min): Show that some temperature words are positive (cool, warm, mild) and some are negative (cold, hot, freezing, boiling). Match feelings: a cool drink (refreshing, positive), a cold drink (uncomfortable, negative), a warm bed (cosy, positive), a hot day (uncomfortable, negative). Drill the positive-negative distinction.
STEP 3 — Extreme words and 'very' (5 min): Show that freezing and boiling are already extreme. Adding 'very' is wrong. 'Very freezing' ✗ — say 'freezing' alone or 'very cold'. 'Very boiling' ✗ — say 'boiling' alone or 'very hot'. Drill examples to fix this rule.
STEP 4 — Hot vs spicy (4 min): Address the confusion briefly (covered in lesson #46). For temperature, use 'hot'. For chilli food, use 'spicy' to be clear. Practise five examples mixing the two: a hot day vs a hot drink vs spicy food.
STEP 5 — Talk about your weather (5 min): Each student describes today's weather, yesterday's weather, and last week's weather using temperature words. Encourage variety — not just hot and cold but warm, cool, mild, chilly. Share in pairs. Partner checks: did the words match the actual conditions?
