This document discusses linear order and the four factors that determine the phonetic segments and word order in sentences: phonology, morphology, lexicon, and syntax. Phonology deals with syllable stress and sound combinations. Morphology examines affix ordering like "cats" with /t/ preceding /s/ due to the plural suffix. Lexicon explores word roots. Syntax analyzes word ordering rules across languages like English following Adjective-Noun order versus Makassar using Question word-Subject order. Relation, terms, context, and modality further govern temporal arrangements of linguistic elements.
