Generate the answer for a given question. The question requires common knowledge of English. Make sure that the answer is in detail, long, consistent with the context, and requires general knowledge of English. To be less repetitive, please vary your language for each question. Give a proper explanation to answer, and if necessary, provide the definition of various terms. And conclude your answer if it's long. If you have used other resources (e.g., Merriam Webster's.) to answer the question, include citations in your answer. You don't need to paraphrase the context of your resources, but make sure that your answer is consistent and complete.

[EX Q]: What's the difference between everytime and every time? I'm a little confused about them, they both seem to have same meaning. Excluding their spelling, are there any other differences between them?.
[EX A]: The difference is that 'everytime' is not a word, and 'every time' means all occurrences: 'Every time I go to the beach, I get a sunburn.' You may be thinking of the difference between 'everyday' and 'every day.' The former is an adjective that can mean either daily or ordinary and common, and the latter is an adverb meaning each day: 'I don't have any fancy clothes. I wear everyday clothes every day.'

[EX Q]: For example, my friend's anniversary is on 3rd August (03/08/2016-dd/mm/yyyy). If I interchange the Month and Day digit and write 08/03/2016 meaning 8th March, is there any special word for this kind of date in English? Like 'Reverse Date' or something. Ignoring the dates after 12th. Editing: I am not confused about date formats here. Think it like, If I want to wish my friend on 8th of March (instead of 3rd August), what should I say him? Like: 'Happy Reversed Anniversary'!?.
[EX A]: While it's difficult to prove a negative, having grown up speaking English and being fairly well-read, I feel safe saying: No, there is no commonly used word for this that would immediately be understood by the majority of people.

[EX Q]: Imagine you're in a bar and order a pint of beer, which is 3.20. You only have a 10 note but want to tip the barkeeper. As you can't use 'keep the change' for obvious reasons, what do you say to tip the barkeeper 80 pence, making the total price 4?.
[EX A]:
I am occasionally in the same situation when I want to tip a taxi driver. Converting to your problem, I would say: Make it 4 pounds. or if that is not clear: Make it 4 pounds and keep the difference. This is in my country (Australia) where tipping is uncommon, however. Edit: Thinking about it even more, sometimes I add the word 'Just' to the front of the sentence. Not sure why.
