Morphology

periodical = period (transparent) = period + ical

The adjective is directly formed from the noun 'period' with the productive suffix '-ical' meaning 'relating to or occurring at intervals', so learners can transparently infer the meaning.

Etymology

Periodical comes from the same root as period, which means a 'length of time' or a regular cycle and comes from peri- meaning 'around'. So, something periodical happens again and again at regular times.
