Morphology

fidelity = faith (semi-transparent) = fidel + ity

The meaning 'loyalty, faithfulness' maps clearly to 'faith'/'faithfulness' conceptually, but the stem in the word ('fidel-') does not match the common English form 'faith', so the morphological relation may not be fully obvious to learners.

Etymology

The word fidelity comes from the Latin fidelis, meaning 'faithful', and from the root fid-, 'to trust', just like in faithful and confide. So, fidelity means loyalty and being true to people or promises.
