Final answer:
The division of 'tables' into 'table - s' is based on morphemes, where 'table' is the root morpheme and '-s' is a suffix indicating plurality.
Step-by-step explanation:
The division of the word 'tables' into 'table - s' is based on morphemes. A morpheme is the smallest grammatical unit in a language and is a word component that carries meaning. In this case, 'table' is the root morpheme that signifies the object, and '-s' is a morphemic suffix that indicates plurality. This division is not based on syllables, which are units of pronunciation, as 'tables' is a two-syllable word ('ta-ble-s') but the division presented is not along syllabic lines.
