hormonal

The word 'hormonal' is a modern scientific formation built directly upon the noun 'hormone'. The term 'hormone' itself was coined in the early 20th century by English physiologists Ernest Starling and William Bayliss from the Greek verb horman, meaning 'to set in motion, urge on, or stimulate'. This etymological choice perfectly captures the function of these chemical messengers, which are secreted into the bloodstream to stimulate or regulate activity in distant target organs and tissues. By adding the common adjectival suffix '-al', derived from Latin -alis, the word 'hormonal' was created to describe anything pertaining to or influenced by these physiological activators. Over time, its usage expanded beyond strict physiology into popular discourse, often describing states of emotional excitability metaphorically linked to endocrine activity.

Structure: hormon (hormone) + al (adjective suffix) - hormon: From Greek hormōn (that which sets in motion, present participle of horman to urge on). The base noun in English. - al: A suffix of Latin origin (-alis) used to form adjectives meaning 'of, relating to, or characterized by'.
