Was ist can? Aussprache und Verwendung im Englischen

Let's break down how to use "can" in English. It's a surprisingly versatile word with a few different meanings and uses. Here's a comprehensive guide:

1. Ability (Most Common Usage):

• Meaning: "Can" most commonly expresses the ability to do something. It means you possess the skill or capacity for an action.
• Structure: Subject + can + verb
• Examples:
  • "I can swim." (I have the skill to swim.)
  • "She can speak French." (She has the ability to speak French.)
  • "They can lift heavy things." (They are physically capable of lifting heavy things.)
  • "Can you help me?" (Are you able to help me?)

2. Permission (Asking and Giving):

• Meaning: “Can” is often used to ask for or give permission. This is especially common in informal contexts.
• Asking for Permission: Subject + can + I/you/we/they + verb?
  • “Can I borrow your pen?” (Permission to borrow)
  • “Can we leave early?” (Permission to leave)
• Giving Permission: Subject + can + subject (pronoun) + verb.
  • “You can go home now.” (Permission granted)
  • "He can stay longer." (Permission granted)

Important Note: While "can" is frequently used for permission, "may" is often considered more formal and polite for asking for permission. For example: “May I borrow your pen?”

3. Possibility/Likelihood (Less Common):

• Meaning: "Can" can sometimes express a possibility or likelihood, though "might" or "may" are often better choices for this.
• Examples:
  • "It can rain tomorrow." (There's a possibility of rain.) – “Might” or “may” sound slightly more formal.
  • “He can be very difficult to please.” (He might be difficult to please.) – Again, "might" is often preferred here.

4. Present Simple Tense (with "be" - less common, but important to know):

• Meaning: “Can” can be part of the present simple tense to express one's characteristics or capabilities. (Think of it as "is able to")
• Structure: Subject + can + be + adjective/noun
• Examples:
  • "He can be very kind." (He is able to be kind.)
  • "She can be a little shy." (She is able to be shy.)

Key Differences Between "Can" and "Could":

• "Can" – Present ability, asking for permission (informal), possibility

• "Could" – Past ability, polite requests for permission, hypothetical situations, suggestions.

  Example: "I can swim" (Present ability) vs. "I could swim when I was younger" (Past ability) vs. "Could you please close the door?" (Polite request)

Here's a quick summary table:

Usage	Meaning	Example
Ability	Possess a skill	I can play the guitar.
Permission	Requesting/Granting	Can I have a cookie?
Possibility	Likely/Possible	It can snow in winter.
Present Tense	Ability/Characteristic	He can be very patient.
