Linear relations of words in connected speech are called syntagmatic relations or the relations on the horizontal level. Syntagmatic relations define the meaning of a word when it is used in combination with other words in speech. Words put together in speech make functional units called phrases or word groups also called word combinations or collocations. The word group is the largest two-facet functional lexical unit (assuming that the word is the basic lexical unit) comprising more than one word on the syntagmatic level of analysis.
