arousals
Arousal is the state of being physically or mentally activated — like your body and brain 'waking up' in response to something exciting, threatening, or stimulating. Think of it as your internal alarm system turning on: heart races, senses sharpen, and attention locks in — whether you're about to give a speech, hear a loud noise, or feel romantic attraction.
During the horror movie, her arousal spiked every time the music got louder.
Athletes often use controlled breathing to manage pre-race arousal and stay focused.
Sexual arousal involves complex interactions between the brain, hormones, and the nervous system.

Teachers sometimes use surprising questions to boost students' cognitive arousal and improve learning.
ous
Comes from the Latin suffix '-ōsus' (via Old French '-ous'), meaning 'full of' or 'characterized by'. It forms adjectives (e.g., 'dangerous', 'glorious') and, by nominalization, nouns like 'arousal' — where the '-al' suffix further converts the adjective 'arousing' into an abstract noun. Examples include 'cautious', 'gracious', 'fabulous', and 'arousal' (from 'arouse' + '-al').
arouse
The verb 'arouse' is the direct etymological source of 'arousal'. It derives from Middle English 'arisen' (to rise up), influenced by Old French 'es- + reuser' (to raise again), ultimately from Latin 'resurgere' (re- + surgere, 'to rise'). Though 'arousal' itself is not built from classical Latin/Greek roots, its core semantic origin lies in the idea of 'rising up' — physically, emotionally, or physiologically. Examples include 'arouse', 'arousal', 'arousing', 'aroused'.
