1“Dear Reader“, to write in a polite way, we do not write any more only „Lieber Leser“, (for dear reader) It has to be “Liebe Leserin und Leser” or “Geehrte Leserin und Leser”, otherwise the people here feel offended
2 “Thank you” translated as “Vielen Dank” based on the context
3 “Thank you” translated as “Ich danke Ihnen” based on the context
4 “Sincerely”, to write in a polite way, I have to use: Mit freundlichen Grüßen (3 words). Not only „Grüße“ or so … that would be impolite

12 “you”: In Greek some endings/suffixes indicate much more than you can imagine.
Take for example, our case. The verb “spot” is conjugated as follows:
I spot/ανακαλύψω-here the ending/suffix “”ω”” indicates the first person singular without mentioning the subject “I”
You spot-singular-/ανακαλύψεις- same as above, suffix.ending “εις”
He, she, it spots/ανακαλύψει-same as above, suffix/ending “ει”
We spot/ανακαλύψουμε-same as above, suffix, ending “”ουμε”
You spot-plural-> plural of politeness(that is, if you are still referring to one person, but you want to be polite, since he/she/it may be anonymous to you and you do not know him/her/it, you use this kind of plural)/ανακαλύψετε-same as above, suffix/ending “ετε”
They spot/ανακαλύψουν-same as above, suffix/ending “”ουν””
