The word consists of the negative prefix 'dis-' and the verb 'qualifizieren' (to qualify). So it literally means to deny someone a qualification or declare it invalid.

When someone makes themselves unsuitable, the verb is used reflexively with 'sich' (oneself). The position or task for which someone disqualifies themselves is connected with the preposition 'für' (+ accusative).

to exclude / rule out
Both verbs can mean keeping someone out of a competition, race, or exam. Disqualifizieren is used specifically when a rule violation or lack of eligibility is the reason; ausschließen is more general. Therefore, disqualifizieren is more precise for a penalty due to a rule violation.
