Q: For example, let's say I'm copying instructions by hand. The original instructions say: Multiply the first by the second Integrate the third with the fourth Integrate the third with the fifth And on a page I write: Multiply the first by the second Integrate the third with the fourth '' with the fifth I know this example is silly, but hopefully it's clear what I mean. What is this called?.

Q: How should you reply to 'what's up?'.

A: 'What's up' means 'What's happening.' I usually just reply 'nothing.' because nothing is happening to me. But, there are alternatives, such as the usual reply to a greeting: Not much Nothing. Yourself? I'm good, yourself? Good. How are you? However, if there is something that you would like to tell the other person e.g. You've sold your car, it might go like this: A: What's up? B: I've sold my car. A: Good on you mate!

Q: The first time I encountered the word 'gondola' was as a 20 year old on her first visit to Venice. Gondolas, to me, were written in my memory as a flat, fancy, romantic (and expensive to ride) boat structures that traverse the canals of Venice, Italy. But soon thereafter, on my first visit to Banff, Canada (Canadian Rockies) -- Gondolas was also the term for ski-like lifts (enclosed from the elements) to get from the bottom to the top of steep mountains (vice versa). What is the etymology of 'gondola'? And how did it develop to reference two completely different transportation devices? One on water, the other on mountains? What is the relationship besides their obvious transportation connect?.

A:
Some of the successive meanings given in the OED are: 1a. ' A light flat-bottomed boat or skiff in use on the Venetian canals, having a cabin amidships and rising to a sharp point at either end; it is usually propelled by one man at the stern with a single oar.' U.S. A large flat-bottomed river boat of light build; a lighter; used also as a gun-boat. 4a. '= gondola-car n. U.S.', which is glossed as 'U.S. a railway car having a platform body with low sides.' 4b. 'An elongated car attached to the under side of a dirigible balloon or airship. [German, Dutch gondel.] Also transf., applied to a structure that resembles such a car in its purpose and mode of attachment.' 4c. 'The car attached to a ski-lift. Also gondola lift.' So the crucial step appears to be the cabin of an airship (which is long and low), and then a cabin suspended from something. This kind of semantic drift is very common.
