Question: What is the antonym of the word destination. Here is some context: Every train has a destination and a ____? I was thinking it might be origin but I've never encountered that word used in this context so I'm not sure - there might be a better word.

Answer: According to a Google search, the word origin is used as the opposite of destination on several pages on the Amtrak web site. Amtrak is the largest train operator in the United States. Here are a few examples: This schedule lists the Origin and 'Destination' of various routes. The Interactive Route Atlas page says the following: Once you have selected origin and destination stations by one of the methods above, click on the 'Go' button to send your custom route request. The Multi-Ride Ten-Ride Ticket page says the following: Ten-ride tickets are valid for ten rides within a 45-day, 60-day or 180-day period depending on your origin and destination cities.


Question: As an adverb, what is the difference between forward and forwards?.

Answer: The OED says this The present distinction in usage between forward and forwards is that the latter expresses a definite direction viewed in contrast with other directions. In some contexts either form may be used without perceptible difference of meaning; the following are examples in which only one of them can now be used: 'The ratchet-wheel can move only forwards'; 'the right side of the paper has the maker's name reading forwards'; 'if you move at all it must be forwards'; 'my companion has gone forward'; 'to bring a matter forward'; 'from this time forward'. The usage of earlier periods, and of modern dialects, varies greatly from that of mod. standard English. In U.S. forward is now generally used, to the exclusion of forwards, which was stigmatized by Webster (1832) as 'a corruption'.


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:
I don't know how you can explain to people in general that it's grammatically incorrect, but here is one idea: when you go to a James Brown tribute concert and the singer says 'Get up offa that thing' what you could do is to trounce the security guards, climb on to the stage, pounce onto the singer, grab the microphone and say 'In fact you should be saying not 'get up offa that thing' but 'get up off that thing' since 'offa' is grammatically incorrect.' I'm sure everyone will thank you for your grammatical corrections. Being serious for a moment though, it's very difficult to decide what is or is not 'grammatically correct'. E.g. in the UK we say 'outside my house' but US people often say 'outside of my house'. How can you actually decide which of these two is grammatically correct? Unfortunately it's not possible since English grammar is not a science like physics but merely a description of what people actually do, and that has changed very significantly over the years. If I was teaching someone English I would definitely say 'off' is correct and 'off of' is wrong, but this kind of decision is based on intuition, based on the usages of educated native speakers.
