The word 'symbolical' is a layered adjectival formation built upon the Greek noun 'symbolon,' which originally denoted a physical object broken in two as a token of identity or pledge between two parties. This concrete sense of a token representing an agreement evolved into the abstract concept of a sign representing an idea. The Greek adjectival suffix '-ikos' was Latinized into '-icus' and then into English '-ic,' attaching to 'symbol' to create 'symbolic,' meaning "of or pertaining to a symbol." The additional Latinate suffix '-al' was later appended, a common practice in English to reinforce or slightly formalize the adjectival form, resulting in the double-suffixed 'symbolical.' The term's logic traces a path from a tangible token of recognition to the modern abstract sense of serving as a representative figure or emblem.
