Frequently Asked Questions

Does 'teorías' always have an accent mark?

Yes. The accent on the 'í' is necessary to separate the vowels and show that the stress falls on the 'i' (te-o-rí-as).

Is it different from 'hipótesis'?

In formal science, a theory is a well-tested explanation, while a hypothesis is a starting guess. However, in casual Spanish, people often use 'teorías' to mean any guess or idea.
