Oversættelse - Tyrkisk-Engelsk - Gerçek yalnızlık

The - at the start of your paragraph is not necessary.

''Real solitude is the solitude of one who lives not on his own but within the crowd and who is aimlessly dispersed hither and thither.''

''with the crowd'' or ''in a crowd''

''Real solitude is the solitude of the one who lives not on his own, but within the crowd, and who wanders aimlessly.''

It's better.

kendin,
this translation is not at a poll yet, that means it still hasn't been checked by an expert.
Please, wait until the expert in charge asks for your help to give your suggestions.
Moreover, why do you require a translation if you think you can do a better translation yourself?
