Syntagmatic analysis
（重定向自Syntagm）
In semiotics, syntagmatic analysis is analysis of syntax or surface structure (syntagmatic structure) as opposed to paradigms (paradigmatic analysis). This is often achieved using commutation tests.
Syntagmatic means one element selects the other element either to precede it or to follow it. For example, the definitive article "the" selects a noun and not a verb.
