question:
Question: In conversation sometimes I'll say something like this: What's that do? which uses "s" as a contraction for "does". Is this a "real" contraction, or is it incorrect usage of a contraction?
Answer: According to Merriam-Webster and Dictionary.com, "what's" is short for: "what is" (What's the matter?) "what has" (What's happened to the car?) "what does" (What's that mean?) So it appears that "What's that do?" is grammatically correct. Merriam-Webster: what's Dictionary.com: what's.
answer:
yes

question:
Question: For example, for the original quote we shall use, "One swallow does not a summer make". If someone were to say "One good quote does not a philosopher make" (No dig at Aristotle intended...), or "A fancy suit does not a businessman make". Essentially, a clear allusion to a quote, but not the quote itself.
Answer: I think you are looking for 'to paraphrase': The adaptation or alteration of a text or quotation to serve a different purpose from that of the original. (AHD).
answer:
no

question:
Question: Does English use the word thou in situations nowadays? For example, to humiliate an opponent by being overly familiar?
Answer: In a very specific technical usage, yes. "thou" is a jargon abbreviation for "one thousandth of an inch" and crops up in machining. Also, automotive industry has to measure fine tolerances, so older petrol engines may have their spark plug gaps measured in inches and be stated as "50 thou" or similar, and pistons may have tolerances in thou. Any workshop engineer using lathes and fitting parts together closely would be familiar with this term even in metric countries. Modern CNC workshops are much more likely to work in metric. The exception would be Americans who end up working in both measurement systems. Aside, in this context "tenth" means "tenth of a thousandth of an inch" and not "tenth of an inch" It is never said as "ten-thousandth of an inch" because that could be misheard for "ten x thousandths of an inch" (ie a hundredth of an inch) in a noisy machine workshop. The metric equivalent would be microns or micrometres, where "1 thou equals 25.4 microns equals 25.4 micrometres".
answer:
no
