Forming phosphoryl (from tRNA with the cost of ATP)-carboxyl (from 
aminoacid) hetero-anhydride  is called aminoacid activation. The 
anhydride formed btw tRNA and aminoacid not only facilitate the 
formation of peptide bond (phosphate is good leaving group) but also the 
precision of the bond-formation (tRNA is specific for each aminoacid and 
recognize the precise code on mRNA in robosome). Sorry if confused.
