Morphology

disabler = disable (transparent) = dis + able + er

The noun is a regular agent or instrument formation from the verb 'disable', meaning someone or something that disables.

Etymology

The word disabler is built from the prefix dis- ('not' or 'opposite'), the word able ('can'), and the ending -er ('one who' or 'something that'). So a disabler is something that makes something 'not able', which is why it stops a device, program, or function from working.
