What does administer mean?
Administer is a formal verb with two principal uses. First, it means to give or apply something to someone — most commonly a drug, vaccine, treatment, oath, test, or punishment — usually implying that the act is carried out by someone with proper authority or training: nurses administer injections, judges administer oaths, examiners administer tests. Second, it means to manage or oversee the operation of an organization, institution, legal estate, or system of rules: a trust company may administer a deceased person's estate, and a government department administers the laws under its remit. Both senses carry connotations of official duty, procedure, and responsibility, which is why the word dominates legal, medical, and bureaucratic writing rather than casual conversation. It derives from the Latin administrare, 'to serve or manage,' built on ministrare, 'to serve' — the same root behind 'minister' and 'minor.' Its noun forms include administrator, administration, and the informal abbreviation 'admin.'

When you administer a drug, you're literally acting as its 'servant' — the word comes from Latin ministrare, 'to serve,' which is why it shares roots with 'minister' and 'minor.'

Etymology of administer
Administer comes from the Latin administrare, meaning 'to serve, manage, or direct,' formed from ad- ('to') plus ministrare ('to serve'), itself derived from minister ('servant'). The word entered English via Old French in the late Middle English period, initially carrying strong senses of service and stewardship. Its cognates include ministry, minister, and minor, all tracing back to the same Latin root denoting servitude or subordination — a reminder that to administer originally meant to serve on behalf of a higher authority.
