Root Explanation

Terephthalate is derived from 'terephthalic acid', which comes from 'terephthalic' (from 'terephthalic acid', a compound derived from the condensation of phthalic anhydride and paraxylene). The term 'terephthalic' itself is formed from 'terephthalic' (from 'terephthalic acid', a compound used in the production of polyester) and '-ate' (a suffix used in chemistry to denote salts or esters of acids). Thus, terephthalate refers to a salt or ester derived from terephthalic acid.

Memory Tip

Think of 'terephthalic acid' as the base compound, and remember that 'terephthalate' refers to the salts or esters made from it.
