Morphology

confirm = con + firm

Although the word is historically related to 'firm', the modern sense 'verify or establish as true' is not a meaning that most B1 learners could reliably derive from con- + firm.

Etymology

The word confirm comes from the parts con- 'together' and firm 'firm' or 'strong'. Think of making an idea or fact firm with proof, so to confirm something is to make it certain.
