Byl jasný, studený dubnový den a hodiny odbíjely třináctou...
O mnoho let později, tváří v tvář popravčí četě, vzpomněl si plukovník Aureliano Buendía na ono vzdálené odpoledne, kdy ho otec vzal k cikánům, aby si prohlédl led.
I love you both <3
how would you translate "that book begins with a strange sentence?
Are there rules when to explicitly use with (s) in a sentence?
It is better to nto think about it as some implicit s.
You use s when there is really something with something. Not when something is done by means of something. And then each verb can have its own rules about which case it uses and which prepositions.
really something with something -> would "together" be a good rule of thumb? I am going there (together) with you, s tebou?
Yes, s tebou.
Also We are with you. (supporting) Jsme s vámi. The verb to be/být really requires it, without the "s" it would be something different (We are you).
