Etymology
the word 'cyclical' traces its lineage to the ancient greek noun 'kyklos', meaning circle, wheel, or any round body. this root was adopted into late latin as 'cyclus' and entered english, forming the basis for words related to circular patterns. the adjectival suffix '-ical' is a compound from latin, combining '-ic' (pertaining to) and '-al' (characterized by), used to form descriptive terms. thus, 'cyclical' literally means 'characterized by or relating to a circle,' which semantically evolved from describing physical circularity to denoting any process or phenomenon that recurs at predictable intervals, like the turning of a wheel.
Analysis
cycl (from greek 'kyklos', meaning circle, wheel, or cycle; functions as the root conveying the core concept of circular motion or recurrence). ical (from latin suffix '-icalis', via english '-ic' and '-al'; functions as an adjective-forming suffix meaning 'of, relating to, or characterized by').
