Claimed by the inventors to be from the supposed past tense, being coined when they realised after much thought (whence "thunk") that the type of an argument in ALGOL 60 could be predetermined at compile time; not, as is sometimes claimed, from the interjection, being the supposed sound made by data hitting the stack or an accumulator
thunk - Computer Definition
In a PC, to execute the instructions required to switch between segmented addressing of memory and flat addressing. A thunk typically occurs when a 16-bit application is running in a 32-bit address space, and its 16-bit segmented address must be converted into a full 32-bit flat address. On the other hand, if a 32-bit program calls a 16-bit DLL, then the thunk is in the opposite direction: from 32 bit to 16 bit.
