"trusting"
The name Fidencio is commonly a male name from the "Spanish" origin that means "trusting".
Fidencio is the Spanish form of the Latin personal name Fidentius, which is formed from the Latin participle fidens (genitive fidentis), meaning "trusting" or "confident", from the verb fidere, "to trust". The corresponding Italian form of the same name is Fidenzio. The name is therefore built on a Latin root rather than a Spanish one, and it belongs to the group of Spanish masculine names inherited directly from Latin.
The pronunciation of Fidencio is fee-DEN-see-oh.
