What does belfry mean?
A belfry is the section of a tower or steeple designed to house bells, whether in a church, cathedral, town hall, or similar building. In everyday usage the word most often refers to the enclosed chamber at the top of such a tower where the bells are actually hung and rung, though it can also denote the entire bell tower itself. Belfries are typically accessed by narrow spiral staircases and often feature louvred openings that allow the sound of the bells to carry while sheltering them from the weather. Beyond its literal architectural sense, belfry has entered idiomatic English through the expression 'to have bats in one's belfry,' a humorous way of suggesting that someone is slightly mad or eccentric — an image drawn from real bats roosting in the dark recesses of church towers. The word carries no strong connotation of its own and is equally at home in architectural description, local history, and casual conversation.
The part of a tower or steeple in which a bell or set of bells is hung.
"From the belfry, the view stretched across rooftops to the distant hills."
Sometimes extended to mean the whole bell tower, especially in older usage.
A bell tower considered as a complete structure.
"The cathedral's detached belfry was built in the fifteenth century."
Standard pluralisation: the '-y' becomes '-ies' following a consonant.
"The region is famous for its medieval belfries, several of which are UNESCO World Heritage sites."
The phrase 'to have bats in the belfry' — meaning to be slightly crazy or eccentric — comes from the idea of bats nesting in the dark upper reaches of a church tower.

Etymology of belfry
Belfry entered Middle English from Old French 'berfrei' or 'befroi', meaning a siege tower or watchtower, and its earliest English sense referred to a movable siege tower rather than anything to do with bells. The word's ultimate origin is debated; it may derive from a Germanic compound related to 'berg-' (protection) and 'frid-' (peace), though this etymology is uncertain rather than established fact. Over time the word became associated with towers housing bells, partly through folk association with the word 'bell'. A cognate form survives in Italian as 'campanile' is unrelated, but the French 'beffroi' remains a direct relative.
How belfry is actually used
