Word is the basic unit of language that has meaning. There are two levels to studying word meaning: syntagmatic looks at relationships between words, and paradigmatic compares words. Most English words have multiple meanings. Analyzing polysemantic words involves looking at the system of meanings and semantic components within each meaning. Semantic components include denotative, the core concept, and connotative, associated meanings. Context is important to determine which meaning is intended when a word has multiple meanings. Studying how words combine in typical contexts, or collocations, provides insight into semantic structure. The same meaning can be conveyed through different word combinations.
