Why does this sentence ご飯を食べてから部屋を掃除してください。 has から?


Why does this sentence

> ご飯を食べてから部屋を掃除してください。

has

> から

Considering that the translation given is

> After eating, please clean your room.

I thought with the given sentence it should be translated along the lines of
"Since you have eaten - clean your room". With that "since" being derived from
から.

Can someone please explain this nuance in both cases?




「te-form + から」(「連用形 + て + から」) means "After doing~~".  
食べ **て** から → after eating

「end form/終止形 + から」(「dictionary form + から」「連用形 + た + から」 etc.) means
"Since/Because (someone) do/did~~".  
食べ **る** から → since/because (you) eat  
食べ **た** から → since/because (you) ate
