Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no". An acceptable answer is consistent with the context in question, detailed, long, and uses general knowledge of English. Answers that are not definite and suggest a variety of options are not acceptable answers.

Question: Is there a name for these kind of doubled words? For example: hanky-panky flim-flam hoity-toity boo-hoo zig-zag Note that some rhyme and others do not. 
Answer: I believe the word you're looking for is reduplication. From Wikipedia: Reduplication in linguistics is a morphological process in which the root or stem of a word (or part of it) or even the whole word is repeated exactly or with a slight change. Wiktionary gives specific types: Exact type: acute-null accents; baby-talk-like bye-bye, choo-choo, night night, no-no, pee-pee, poo-poo, etc. Ablaut type: acute-grave accents, high-low vowels, front-back vowels. bric-a-brac, chit-chat, criss-cross, kitty-cat, knick-knack, jibber-jabber, splish-splash, zig-zag, sing-song, etc. Rhymed type: acute-acute accents, varied initials. claptrap, hokey-pokey, honey bunny, razzle-dazzle, slim jim, super-duper, teeny-weeny, wingding, etc.
yes

Question: How can I explain to people that the phrase off of is grammatically incorrect? I've heard this phrase used a lot, especially by Americans (though they aren't the only ones). In my understanding, off of should usually be replaced by off, as in, I took the book off the shelf as opposed to I took the book off of the shelf Am I wrong? Or is there perhaps some simple way I can explain this to most people? 
Answer: In my opinion, if you mean to say, "off of", then you should instead say, "from". For example, "Take the book off of the bookcase", when, "Take the book from the bookcase", is preferable. As I understand it, the expression "off of", is an Americanism, but the pseudo-antonym, "on of", is rarely (if not never), found in any language as far as I am aware.
no

Question: When should whilst be used instead of while? For example, should I use the first or the second sentence? They don't do this whilst they do that. They don't do this while they do that. Which would be correct? 
Answer: The two words 'while' and 'whilst' mean the same thing. They could be considered alternate pronunciations of the same word, similar to among/amongst or further/farther. 'While' came first, and then 'whilst' was derived from it. But they are not used with the same frequency and they give different 'feels'. 'While' is much more common (from Google nGrams) 'Whilst' sounds archaic, affected, or hyperacademic (which means no one in academia uses it). To Americans, 'whilst' sounds British, but at least in print, there is very little difference in the frequencies of the two words between AmE and BrE (via Google nGrams) In the end, it is correct grammar to use them interchangeably, but it is bad style...uh sorry, not the current fashion to use 'whilst'. No one (at least not in formal writing, like for newspapers or academic writing) uses 'whilst' anymore. It may be common and accepted in certain varieties of English (say Indian English) but is very jarring in standard English. However, in the 18th century the two were on more equal terms. The classic study of text analysis by Mosteller and Wallace to help discover the authorship of the Federalist papers was based primarily on the use of differentiating pairs like this.
