Does anyone pronounce caricature with the emphasis on the 2nd syllable rather than the first? Example: caRIcature vs. CAricature
The OED only lists one pronunciation, with a primary stress on the first syllable and a secondary stress on the last:
caricature, n. /ˈkarɪkəˌtjʊə/
The Merriam-Webster dictionary lists several variants, but all have the same stress pattern as the OED:
caricature, n. \ˈker-i-kə-ˌchu̇r, -ˌchər, -ˌtyu̇r, -ˌtu̇r, -ˈka-ri-\
If you're not familiar with stress markings, the symbol \ˈ\ precedes the syllable with main stress in a word, and the symbol \ˌ\ precedes any syllable with secondary stress.
This is not to say that nobody ever pronounces it this way, but it is not a commonly accepted pronunciation. It may be spoken as an unintentional error, or it may be done for humorous effect.
