Antidiuretic is an adjective describing a substance or action that reduces urine production by affecting the kidneys, or more broadly something that conserves bodily fluids. In medical contexts it also refers to hormones like vasopressin that regulate water balance. The term combines roots meaning against diuresis and is used in clinical discussions and pharmacology.
US: rhotic /r/ in 'jure' and a clear /jʊr/ cluster; UK: weaker post-vocalic r, more centralized /ə/ in non-stressed vowels; AU: similar to US but with broader vowels and flatter intonation. Vowel changes: /æ/ in 'ant' is near vowel centralization; /aɪ/ in 'di' remains a clean diphthong. Consonants: keep /d/ alveolar stop precise; ensure /t/ is unreleased or lightly released depending on speed. IPA references used.
"The antidiuretic effect of vasopressin helps the body retain water during dehydration."
"Doctors prescribed an antidiuretic to treat certain cases of diabetes insipidus."
"During the study, researchers measured the antidiuretic response to different hydration levels."
"The patient was monitored for signs of excessive antidiuretic activity, which could lead to water intoxication."
Antidiuretic comes from the prefix anti- (against), the combining form diuretic (diuresis-related, from Greek di ousa ‘through urine’), and the common medical suffix -etic. The root diuretic originates from Greek diourētikos (through urine) from di- ‘through’ + ouron ‘urine’. Anti- meaning against, combined with diuretic describes a substance that counters diuresis. The term was adopted into English medical vocabulary as pharmacology and physiology formalized the concept of substances that reduce urine output, notably vasopressin analogs and synthetic antidiuretic hormones. First known usage appears in medical texts of the late 19th to early 20th century as endocrinology and nephrology advanced, with the discovery of hormonal controls of renal water reabsorption. Over time, the word has been solidified in clinical discourse and pharmacological naming conventions for both endogenous (vasopressin) and synthetic agents that regulate body water balance.

Say /ˌæntiˌdaɪˈjʊrɛtɪk/ in many US and UK contexts, with stress on the third syllable (the -rye- or -jure- cluster). The sequence anti- + di- + ure + tic forms a three-beat rhythm: an-ti-DI-uRE-tic, with the main stress on the penultimate essential syllable in many pronunciations. Tip: keep the 'jure' as a single syllable with a 'dy' or 'jyu' quality, avoiding a drawn-out 'di-ure' diphthong. Audio reference: consult medical pronunciation resources or Cambridge/Oxford audio dictionaries for variety across accents.
Common errors include: misplacing stress (trying anti-DI-u-RET-ic instead of anti-DI-ure-tic with correct -ure- as a separate unit), swallowing the schwa in the second syllable, and mispronouncing the 'ure' as a hard 'you-ree' rather than the concise /juːr/ sound. Correction: practice the sequence anti- /ˈænti/ then /ˌdaɪ/ + /ˈjʊr/ + /ɪk/, keeping the -r- glottal to a minimum and using a tight, rounded lips for /juːr/.
In US: syllables lean toward /ˌæntiˌdaɪˈjʊrɛtɪk/ with a rhotic /r/ in 'jure'. UK/RP tends to /ˌæntiˌdaɪˈfjʊərɪtɪk/ or /-jʊˈrɛtɪk/, with non-rhoticity reducing post-vocalic r. Australian usually aligns with US but with slightly flatter vowels and a more open /ɪ/ to /ə/ transitions; the /ju/ can approach /jə/ in rapid speech. IPA notes: pay attention to rhotic /r/ presence and the lax vowels in 'aria' segments.
It combines three tricky clusters: anti- (unstressed to weak vowels), di/ure (the /aɪ/ diphthong followed by a quick /jʊr/ sequence), and -t ic ending. The blending of /ˌdaɪ/ and /ˈjʊr/ can cause a glide failure or a too-strong /r/ in non-rhotic contexts. Focus on keeping the /ɪ/ vs /iː/ distinction short, and the /j/ sound tied to the /ʊr/ rather than an Americanized /jʊər/ blend.
A unique aspect is the apostrophized tri-syllable rhythm where the second strong vowel is /aɪ/ in 'di', followed by a compact /ˈjʊr/ sequence in 'ure'. Learners often overemphasize the 'di' as a separate syllable; instead, gently fuse /ˌdaɪ/ with a crisp /jʊr/ to avoid a heavy 'di-ure' split. This helps maintain natural medical-cunch pronunciation that clinicians expect.
