Explanation at your level:
Use which when you want to choose. If you have two pens, you ask: 'Which pen is yours?' It is simple and helps you get the right thing. Use it when you have a small group of things to pick from.
You use which to ask for specific information. For example, 'Which bus goes to the city center?' It is very common when you are traveling or asking for directions. It helps you distinguish one item from another.
At this level, you start using which in relative clauses to add extra information. 'The house, which is painted blue, is mine.' It connects ideas smoothly and makes your sentences sound more sophisticated and connected.
Nuance is key here. You might use which to refer back to a whole clause: 'He was late, which annoyed the boss.' This shows you can handle complex sentence structures and express relationships between events clearly.
In academic or professional settings, which is essential for precision. It helps avoid ambiguity in reports or essays. You might use it in phrases like 'the extent to which,' which demonstrates a high level of control over formal English.
Mastery involves understanding the subtle stylistic choices between that and which in restrictive vs. non-restrictive clauses. Using which correctly in complex, literary, or technical prose shows a deep command of English syntax and clarity.

Hey there! Think of which as your personal selector. When you have a group of things—like a basket of apples or a list of book titles—and you need to know exactly which one is the right one, you use this word.
It is different from what because what is usually for open-ended questions, while which implies you are choosing from a specific, limited set. It is a super helpful word for getting clear, specific information in your daily conversations.
The word which has a very long history, dating all the way back to Old English! It comes from the word hwilc, which was a combination of hwi (why) and lic (like).
Essentially, it originally meant 'of what sort' or 'what like.' Over centuries of language evolution, it shifted from asking about the 'sort' of thing to identifying a specific item from a group. It shares roots with other Germanic languages, making it a cousin to words like the German welch.
You will use which whenever you need to narrow down options. Common pairings include which one, which way, and which side. It is very versatile and works in both casual chats and formal business emails.
In formal writing, you might see it used in relative clauses, like 'The book, which I read yesterday, was great.' In casual speech, it is the go-to for making decisions: 'Which shirt should I wear?'
While which is a functional word, it appears in several fixed phrases. Which is which helps us distinguish between two similar things: 'I can't tell which is which!'
Another common expression is which way the wind blows, meaning to observe a situation before acting. We also use in which case as a formal way to say 'if that happens.' These phrases add nuance to your English, making you sound more natural and fluent.
Pronounced /wɪtʃ/ in both US and UK English, it rhymes with rich, stitch, and pitch. The 'w' is often aspirated, especially in older or regional dialects.
Grammatically, which is a determiner that can precede a noun (e.g., 'Which color?'). It does not change form for pluralization, making it very easy to use. It is a stable, reliable word that fits perfectly into almost any sentence structure involving questions or relative clauses.
