"Phenomenon", "remuneration" and "statistics" have topped a list of the most commonly mispronounced English words.
Speakers also have a problem getting their tongue around "ethnicity", "hereditary" and "particularly", according to the UK body charged with recording public utterances.
The British Institute Of Verbatim Reporters (BIVR) is the UK's leading organisation for professionals involved in taking down speech at court and tribunal hearings.
A poll of its members found the 10 words that Britons consistently find the most challenging to pronounce.
Completing the list are "conjugal", "specific", "processes" and "development".
