What does it mean to weaponize or enrich uranium

Enriched uranium is a type of uranium in which the percent composition of uranium-235 has been increased through the process of isotope separation. Natural uranium is 99.284% 238U isotope, with 235U only constituting about 0.711% of its mass. ... The term oralloy is still occasionally used to refer to enriched uranium. Hope this helps
