Detritus - word I have always mispronounced.

http://dictionary.cambridge.org/dictionary/british/detritus

Gosh I hate finding out I have been saying something wrong all along...

I know what you mean.  I once went to a landscape/nursery and insisted that the plant I wanted was pronounced a certain way in opposition to the man helping me - a guy who worked with plants all day and knew his stuff!!!   

That was almost bad enough to keep me from shopping there again. 

If I may I ask, how were you pronouncing 'detritus'?

I've pronounced it exactly as it sounds in the "US" audio.....

Still can't figure out the correct way to pronounce tinnitus.....my UK hubby pronounces it as I always did prior to moving back and hearing it pronounced completely differently. I defaulted to the 'English way' and DH said I was mispronouncing it. Wouldn't matter, except I have severe tinnitus and occasionally have the need to say the word.
