Questions & Answers about Sumnja je normalna; međutim, ne želim odustati od učenja jezika.

Why is normalna used instead of normalno in Sumnja je normalna?

Because normalna has to agree with sumnja in gender, number, and case.

• sumnja (doubt) is:
  • feminine
  • singular
  • nominative (subject of the sentence)

The adjective normalan (normal) must match that:

• masculine: normalan
• feminine: normalna
• neuter: normalno

So we say:

• Sumnja je normalna. – sumnja (fem.) → normalna (fem.)

You would use normalno in an impersonal sentence, for example:

• Normalno je sumnjati. – It is normal to doubt.
  (normalno here is neuter because the subject is an unspecified situation, like English It is normal…)

Could you also say Normalno je sumnjati instead of Sumnja je normalna? Is there a difference?

Yes, you can, and both are correct, but the focus is a bit different.

• Sumnja je normalna.
  Literally: Doubt is normal.
  You are talking about doubt as a thing and describing it.

• Normalno je sumnjati.
  Literally: It is normal to doubt.
  This is an impersonal construction. You focus more on the than on as a noun.
