Linguistic Note on Dissection
The word dissection is commonly misparsed and consequently mispronounced.
Consequently it can be seen pronounced di-section, where the first syllable is sounded as the English word die.
In extreme cases, it can often also be seen spelt disection, which is always incorrect.
In fact, accurate parsing shows that the first syllable is dis, so pronounced, having the same linguistic purpose as the same syllable as dismember, disassociate, dismiss and so on.
