[Q]: What is the correct version of this common phrase? First come, first serve First come, first served Gramatically, I believe 2. is the correct form. However, it seems that 1. is commonly employed in spoken and even written English.
[A]: The second is correct. It is a form of 'Those who come first are served first.'


[Q]: Please tell the single word for 'to completely root out a disease'.
[A]: Eradicate. Etymology is from Eradicare. Eradicare, in turn, can be traced back to the Latin word radix, meaning 'root' or 'radish.' Although eradicate began life as a word for literal uprooting, by the mid-17th century it had developed a metaphorical application to removing things. Eradication is the reduction of an infectious disease's prevalence in the global host population to zero.


[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'!?.
[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.
