What does this “even” mean?
“How the heck will Kinect swimming even work?” is a nice example of a use of even that I think is genuinely new. At least, certain expressions like “what does that even mean?” and “how does that even work?” have recently become common, and I can’t find clear examples of them that are more than about 15 years old. But perhaps we should see this as rolling the clock back to the 16th century, and taking things up where they left off when even began a five-century detour as a scalar particle.
According to the OED, even started out meaning “flat, level, uniform”, passed through related notions like “equal, coincident, balanced, exact”, and eventually came to be used “in weakened senses as an intensive or emphatic particle”, which might be “Prefixed to a subject, object, or predicate, or to the expression of a qualifying circumstance, to emphasize its identity”.
