✦Grammar Breakdown

IstdieHefeaktivodertot?

1

sein (ist)

‘ist’ is the 3rd‑person singular present of the verb ‘sein’ (to be) and is used for singular nouns.

2

definite article (die)

‘die’ is the feminine singular nominative article; ‘Hefe’ is a feminine noun.

3

noun gender (Hefe)

‘Hefe’ (yeast) is feminine, so it takes the article ‘die’ and the verb form ‘ist’.

4

predicative adjectives (aktiv, tot)

Adjectives used after ‘sein’ stay in their base form (no ending) because they are predicative.

5

coordinating conjunction (oder)

‘oder’ links two alternatives; the sentence asks which of the two states applies.

✕Common Mistakes

  • Sind die Hefe aktiv oder tot?

    ‘Hefe’ is singular, so the verb must be ‘ist’, not ‘sind’.

  • Ist die Hefe aktiv oder tote?

    When used predicatively after ‘sein’, adjectives stay uninflected; ‘tot’ not ‘tote’.

  • Die Hefe ist aktiv und tot.

    ‘und’ creates a contradictory statement; use ‘oder’ to present alternatives.

Cultural Tip

In German households, checking yeast viability is a common step before baking a loaf. The classic test is to dissolve a pinch of sugar in warm (≈35 °C) water, add a teaspoon of yeast, and wait 5‑10 minutes. If it becomes foamy, the yeast is active. Saying ‘Ist die Hefe aktiv oder tot?’ shows you understand this practical tradition and helps you avoid a flat, un‑risen bread.
