Both syntagmatic and paradigmatic analyses contribute to the inherent meaning and understanding of a given language.
Syntagmatic relationships are created with the understanding that components of language fall in a certain order. Letters, words, and sentences in a particular order create meaning. This meaning is created from the lowest levels, stringing certain letters together and building to create meaning by sequencing paragraphs in a particular order. Sequence is a focal point in this area of thought.
Paradigmatic relationships look instead at the way groups of words relate to each other. Adjectives, therefore, can be substituted for each other:
We found a furry cat.
We found a fluffy cat.
Pronouns are examined together:
I want pizza.
We want pizza.
All parts of speech are thus able to fall into similar subgroups, allowing for certain types of substitutions within these subgroups.
Being able to fluently interact with a language—including retrieval of information, creating meaning, summarizing text or events, and creating language with meaning—necessitates the use of both syntagmatic and paradigmatic relations.
