"Do you know this boy?"
Translation:Znacie tego chłopca?
Is There a table somewhere please to summarize especially the Mom and Acc singular and plural forms for this that that these, please. Because right now i am super confused between ten/ta/to/tę/tamtego/ tamte/ tamci...it keeps coming up but it seems what i did week before has now changed... Help!!
"tego" is a form of "this". "tamto" is a form of "that".
"tamto" is neuter Nominative or Accusative. "tego" is either masculine animate Accusative, masculine Genitive or neuter Genitive. Here it is masculine Accusative, "znać" takes Accusative and "chłopiec" is masculine.
I advise you to save the declension table somewhere: https://en.wiktionary.org/wiki/ten#Polish
It is for forms of "ten", but forms of "tamten" are almost identical: you just put tam- at the beginning. The only difference is feminine Accusative, which is "tę" for 'this' but "tamtą" for 'that'.
