Questions & Answers about Mein Bruder ist genauso müde wie ich.

What does genauso … wie mean, and what is the basic pattern here?

The structure genauso … wie expresses equality in a comparison, like English “just as … as” or “equally … as”.

Pattern:

• genauso + adjective/adverb + wie + comparison partner

In the sentence:

• Mein Bruder – subject: my brother
• ist – verb: is
• genauso müde – just as tired
• wie ich – as I (am)

So the whole thing literally means: “My brother is just as tired as I (am).”

Why is it wie and not als in this sentence?

German uses different words for different kinds of comparisons:

• so/genauso … wie = equality: as … as

  • Mein Bruder ist genauso müde wie ich.
    My brother is just as tired as I am.

• … -er als (comparative + als) = inequality: -er than

  • Mein Bruder ist müder als ich.
    My brother is more tired than I am.

Since the sentence says they are equally tired, German must use wie, not als.
If you said genauso müde als ich, it would be incorrect.
