Spanish is classified by its rhythm as a syllable-timed language: each syllable has approximately the same duration regardless of stress.

Spanish intonation varies significantly according to dialect but generally conforms to a pattern of falling tone for declarative sentences and wh-questions (who, what, why, etc.) and rising tone for yes/no questions. There are no syntactic markers to distinguish between questions and statements and thus, the recognition of declarative or interrogative depends entirely on intonation.

Stress most often occurs on any of the last three syllables of a word, with some rare exceptions at the fourth-to-last or earlier syllables. Stress tends to occur as follows:

In addition to the many exceptions to these tendencies, there are numerous minimal pairs that contrast solely on stress such as sábana ('sheet') and sabana ('savannah'); límite ('boundary'), limite ('he/she limits') and limité ('I limited'); líquido ('liquid'), liquido ('I sell off') and liquidó ('he/she sold off').

The orthographic system unambiguously reflects where the stress occurs: in the absence of an accent mark, the stress falls on the last syllable unless the last letter is ⟨ n ⟩, ⟨ s ⟩, or a vowel, in which cases the stress falls on the next-to-last (penultimate) syllable. Exceptions to those rules are indicated by an acute accent mark over the vowel of the stressed syllable. (See Spanish orthography.)
