Questions & Answers about Lepek je důležitý pro chlebové těsto.

Why is the verb je used here?

Je is the 3rd person singular form of the verb být (to be).

The subject is lepek (gluten), which is singular, so Czech uses je = is.

• lepek je = gluten is

This works just like English is in a sentence like Gluten is important.

Why does důležitý end in -ý?

Because důležitý agrees with lepek.

In this sentence, lepek is:

• singular
• masculine inanimate
• nominative (the subject)

So the adjective also appears in the matching form:

• lepek je důležitý

If the subject changed, the adjective form would change too:

• Mouka je důležitá. = Flour is important.
  (feminine)
• Těsto je důležité. = Dough is important.
  (neuter)

So -ý here is the masculine singular form.
