In a way that comes from outside or is not inherent to something.

Extrinsically → It is formed from "ex-" (meaning out of or from) and "trinsic" (from Latin "intrinsecus", meaning inward or internal) with the suffix "-ally" (meaning in a manner). The word "extrinsically" refers to something that is done in a manner that comes from outside or is external to something.
Think of 'out of' ('ex-') and 'internal' ('trinsic') to remember that 'extrinsically' means something that comes from outside.
