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.
