What does fortified mean?
Fortified means strengthened or protected against attack, most classically in a military sense: a fortified city is one ringed with walls, bastions, or other defenses designed to withstand assault. Over time the word broadened to describe anything made stronger or more resilient — a person may feel fortified by encouragement, and an argument may be fortified by evidence. In everyday modern usage it also appears on grocery shelves: fortified cereals, milks, and juices have vitamins or minerals deliberately added, while fortified wines such as port and sherry have had spirits added to boost their alcohol content and stability. Derived from the Latin fortis, meaning 'strong', the word carries connotations of deliberate preparation and defense rather than natural toughness. Whether describing medieval ramparts, enriched foods, or quiet personal resolve, fortified signals that extra strength has been consciously added to withstand pressure or hardship.
Strengthened against attack, or reinforced/enriched in strength or content.
"The monks took refuge behind the abbey's fortified gates."
Frequently used attributively; common in military, architectural, food-labelling, and wine contexts.
Past tense and past participle of 'fortify': to strengthen or protect a place, object, person, or resolve.
"They fortified the bridge with sandbags before the flood arrived."
The same Latin word for 'strong' gives us both 'fortified wine' and 'fortress' — so your bottle of sherry is literally named after a stronghold.

Etymology of fortified
Fortified comes from the Latin fortis, meaning 'strong' or 'brave', via the Old French fortifier, which combined fortis with the suffix -ficare, 'to make'. The verb entered English in the fifteenth century, and the participial form 'fortified' has since served both as an adjective describing strengthened places, foods, and wines and as the past tense of 'fortify'. Its many cousins from the same sturdy root include fortress, fortitude, and fort itself.
