análysi

Análysi is the transliteration of the Greek word ανάλυση, commonly used in several languages to denote analysis—the systematic examination of a subject by breaking it down into its component parts to reveal structure, function, or meaning. Etymology traces the term to Greek ana- meaning up or again, and lýsis meaning loosening or a setting loose, with the concept carried into Latin and other languages.

In practice, análysi appears across disciplines. In mathematics, analysis refers to the rigorous study of limits, continuity, derivatives, and integrals, with subfields such as real analysis and complex analysis. In the sciences, analytical methods involve decomposing a system, measuring variables, and building models to explain phenomena. In data analysis, statistical and computational techniques are used to summarize data, test hypotheses, and infer patterns. In the humanities and social sciences, qualitative analysis examines texts, artifacts, or interview data to interpret meaning, context, and significance.

Methods commonly associated with analysis include decomposition, modeling, comparison, pattern recognition, and critical evaluation. Analytical thinking emphasizes careful reasoning, evidence-based conclusions, and transparency about assumptions. The concept often complements synthesis, with analysis providing the insights that guide the construction of coherent explanations or solutions.

Variants and related terms appear in many fields, such as analytical chemistry (instrumental measurement and interpretation), linguistic analysis, and analytic philosophy.
