Root Breakdown
Root-derivedad- (onto), here assimilated to as-, + serere (join) = to link a claim firmly onto something. To assert is not just to say — it is to attach yourself to a statement and stand behind it. That binding image is why assert always carries force and commitment.

Easily Confused
assert vs claim — Both mean to state something as true, but assert sounds confident and committed (you stand firmly behind it), while claim often hints the statement may be doubtful or unproven ('he claims he was elsewhere' suggests skepticism). Use assert when you want to sound sure; claim when the truth is still open.
