Extra prominence given to one syllable relative to nearby syllables.
In precise terms
Stress is a prosodic prominence relation among syllables. In spoken languages it may be realised through a language-specific combination of pitch, duration and intensity; its placement may be predictable or lexically contrastive.
An example
ˈCV.CV · CV.ˈCV (schematic)
What is going on here
The IPA mark [ˈ] appears before the onset of the syllable with primary stress. These schematic forms contain the same sequence of consonants and vowels but place prominence on different syllables; whether that difference changes a word's identity depends on the language.
Why this matters when you are learning a language
A dictionary's stress mark tells you more than which syllable to say louder. Learners need to notice the cues their target language uses and whether stress follows a rule or belongs to the stored form of each word.
Across languages
Languages differ both in where stress can fall and in how listeners perceive it. Some assign stress predictably from syllable structure or word edges; others use lexical stress, so a change in placement can distinguish words. The balance of pitch, duration and intensity also varies.
