Present participle: kaufend · Past participle: gekauft
The present participle is kaufend, which you use as an adjective for an ongoing action. The past participle is gekauft, which you use with haben in the perfect tenses: the ich form of the Perfekt is habe gekauft, used for a completed action. Keep both forms in mind as you read the examples below, because the present is only one part of how kaufen is used.
How the present of kaufen is formed
The present of kaufen follows the regular weak pattern: take the stem and add the present endings, giving ich kaufe, du kaufst, er/sie/es kauft, wir kaufen, ihr kauft, sie/Sie kaufen. The wir and ihr forms are the ones learners most often get wrong, because they expect a change that is not there — learn the six forms as two groups, the singular forms and the plural forms, and the pattern becomes automatic. The stem never changes in the present for this verb, so the only work is the endings.
The present stem also feeds other tenses: the preterite and Konjunktiv II are built from the same stem family, so learning the present properly makes the rest of the conjugation easier. The participles kaufend and gekauft belong to the same family of forms — learn them together with the present table and you will recognise kaufen in every tense.
When to use the present of kaufen
The present is not a single-purpose tense. Below are the five situations where you will use kaufen in the present most often. Each one comes with a real example, so read the rule, then say the example out loud.
1. To buy a book in the shop — the everyday use
The most everyday use of kaufen is a book in the shop. It covers the ordinary, everyday situations where this verb appears, at home and outside. Example: “Ich kaufe ein Buch im Laden.” — “I buy a book in the shop.”
2. To buy bread and milk in the morning — a second everyday use
Kaufen also covers bread and milk in the morning. This use is very common in everyday speech, and it is the one learners meet next after the first. Example: “Du kaufst Brot und Milch am Morgen.” — “You buy bread and milk in the morning.”
3. To buy a new coat in winter — a third everyday use
In a third everyday situation, you use kaufen for a new coat in winter. The same verb, the same present forms, a different situation — that is why the present is worth learning as a whole table rather than one form at a time. Example: “Er kauft einen neuen Mantel im Winter.” — “He buys a new coat in winter.”
4. Habits and routines
The present tense is the tense of routine. When something happens every day, every week or every morning, the present is the natural choice, and kaufen is no exception. Use time expressions such as jeden Tag, immer or jede Woche to make the routine explicit. Example: “Wir kaufen ein Buch im Laden.” — “We buy a book in the shop.”
5. What is happening right now
The present also describes an action in progress at this very moment. German often prefers the simple present where English would use the continuous form, so a sentence with kaufen in the present can mean both “I do this” and “I am doing this now”. Context tells the listener which one you mean. Example: “Ihr kauft Brot und Milch am Morgen.” — “You buy bread and milk in the morning.”
Present Tense vs Preterite: how to choose
The closest tense to the present is the preterite, and learners mix them up constantly. The rule is simple: the preterite describes a finished action in the past, while the present describes habits and facts that are true now. The three pairs below use the same verb, so the only thing that changes is the time frame — and with it, the tense. Notice how the present sentences use words such as jeden Tag, while the preterite sentences use gestern. Those time words are your best clue when you are choosing a tense.
Present (Präsens): “Ich kaufe ein Buch im Laden.” — “I buy a book in the shop.”
Preterite: “Ich kaufte ein Buch im Laden.” — “I bought a book in the shop.”
The present sentence is about the present moment or a routine; the preterite sentence is about one finished action in the past. That difference — now versus finished — is the whole decision.
Present (Präsens): “Du kaufst Brot und Milch am Morgen.” — “You buy bread and milk in the morning.”
Preterite: “Du kauftest Brot und Milch am Morgen.” — “You bought bread and milk in the morning.”
The present sentence is about the present moment or a routine; the preterite sentence is about one finished action in the past. That difference — now versus finished — is the whole decision.
Present (Präsens): “Wir kaufen einen neuen Mantel im Winter.” — “We buy a new coat in winter.”
Preterite: “Wir kauften einen neuen Mantel im Winter.” — “We bought a new coat in winter.”
The present sentence is about the present moment or a routine; the preterite sentence is about one finished action in the past. That difference — now versus finished — is the whole decision.

Read these eight sentences out loud. They cover all six persons, so by the end you will have seen every form in the table used in a real sentence. Pay attention to the words around the verb — the time expressions, the objects, the other words — because those are what make each sentence sound natural.
“Ich kaufe Brot und Milch am Morgen.” — “I buy bread and milk in the morning.”
“Du kaufst einen neuen Mantel im Winter.” — “You buy a new coat in winter.”
“Er kauft ein Buch im Laden.” — “He buys a book in the shop.”

Common mistakes with kaufen in the present
These are the errors learners actually make with this verb in this tense. Each one shows the wrong version, the right version, and why the correction matters.
Wrong: “Ich kaufen ein Buch im Laden.” Right: “Ich kaufe ein Buch im Laden.” Why: The ich form is kaufe, not kaufen. Kaufen belongs with sie. Mixing the two groups is the most common error with this verb.
Wrong: “Wir kaufen ein Buch im Laden.” Right: “Wir kaufen ein Buch im Laden.” Why: Wir keeps its own form: kaufen, not kaufen. Learn wir and ihr as a separate pair from the singular forms.
Wrong: “Ich kaufen ein Buch im Laden.” (infinitive with a subject) Right: “Ich kaufe ein Buch im Laden.” Why: The infinitive kaufen never takes a subject. After ich you need the conjugated present form kaufe.
Wrong: “Ich kaufe ein Buch im Laden gestern.” (a finished past action) Right: “Ich habe ein Buch im Laden gekauft.” Why: The time word gestern points to the past, so a finished action needs the Perfekt habe gekauft, not the present kaufe.
