fiable
/ˈfjable/ · B2 · adj
reliable, trustworthy, dependable
🤝 fiable = fi (from fiar, to trust) + able → able to be trusted
Spanish fiar means to trust, from Latin fidere. Add the suffix -able and you get fiable: trust-able. English shares the same Latin root in fidelity, confide and confident, so the link to trust is easy to hold.
