his-tuh-RIS-is
/ˌhɪstəˈrɪsɪs/
hysteresis is pronounced his-tuh-RIS-is (/ˌhɪstəˈrɪsɪs/). Hysteresis is a phenomenon in which systems do not immediately return to their original state after the influencing force is removed, showing a lag or memory effect. In science and engineering, it describes path-dependent behavior where output depends on the history of input. The term is used across physics, chemistry, biology, and economics to explain persistent changes despite changing conditions.

"The magnetic material exhibited hysteresis, retaining magnetization after the external field was removed."
"In economics, hysteresis explains how unemployment rates can stay elevated even after a shock subsides."
"The cooling curve showed thermal hysteresis due to phase transitions within the material."
US/UK/AU pronunciation centers the stress on the second syllable: /ˌhɪ.stəˈriː.sɪs/ (US/UK). In Australian speech you may hear a slightly lighter second syllable: /ˌhɪs.təˈriː.sɪs/ or /ˌhɪs.təˈɹiː.sɪs/. Break it into hi-STER-e-sis with the primary stress on the -ri- syllable. Start with /hɪ/ then /ˈriː/ then /sɪs/. Keep the /ɪ/ vowels short in the first and third syllables and lengthen the /iː/ in the stressed second syllable.
Common mistakes include stressing the wrong syllable (placing primary stress on the first or third syllable), and mispronouncing the /r/ and /siː/ sequence as /riːzɪs/ or dropping the /t/ leading to /ˈhɪstərəsɪs/. Correct approach: /ˌhɪ.stəˈriː.sɪs/. Ensure a clear /t/ after /st/ and a full /riː/ vowel; keep the /sɪs/ final cluster crisp rather than flattening to /səs/.
US/UK share the same general pattern: primary stress on the second syllable: /ˌhɪ.stəˈriː.sɪs/. Australian often reduces the second syllable slightly, closer to /ˌhɪs.təˈriː.sɪs/ with a quicker /st/ sequence and a less pronounced /r/ in some dialects. Rhoticity affects the /r/ articulation: strong rhotic in US, non-rhotic in some UK variants, leading to subtle allophonic differences in the /riː/ sequence. Aim for consistent /ːiː/ in the stressed vowel and crisp /s/ endings across all accents.
It combines a cluster /st/ following /hɪ/ with a long /riː/ in the stressed syllable and a final /sɪs/, which challenges learners to coordinate careful alveolar timing and vowel length. The sequence /st/ followed by /ə/ can trigger an anticipatory schwa in rapid speech. Focus on locking the /t/ before the /r/ and maintaining the /riː/ duration, while not allowing the final /s/ to be slurred into /z/.
No silent letters in standard pronunciation. Each syllable contains a phoneme: /hɪ/ (hi), /stə/ (stuh), /ˈriː/ (REE), /sɪs/ (sis). The challenge is accurate articulation of the /st/ cluster, the vowel length in /riː/, and preserving the final /s/ rather than turning it into a /z/ in connected speech.

Hysteresis comes from the Greek word hysterēsis, from hysterēsai meaning to stand behind or lag behind. The term was adopted in scientific usage in the 19th century as a label for lagging behavior observed in magnetic materials and other systems. Its core idea—dependence on the system’s history—was extended beyond physics to chemistry, biology, economics, and engineering. The Greek root hyster- implies behind or later, while -sis denotes a process or condition. Early researchers used hysteresis to describe magnetic lag, gradually applying the concept to broader phenomena where the current state could not be deduced from present inputs alone. The word’s usage expanded with advances in materials science, nonlinear dynamics, and system theory, making hysteresis a foundational concept for memory effects and irreversible processes across disciplines.
