[edit] Etymology 3

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
