What does enfilade mean?
Enfilade refers to a striking arrangement in which rooms, doors, or windows are aligned along a single straight axis, allowing an unbroken view through an entire sequence — a technique beloved of Baroque and neoclassical palace architects, who used it to create dramatic perspectives of depth and grandeur. The word also has a military meaning: gunfire directed lengthwise along an enemy's line, such as down a trench or road, which exposes targets that would be protected from frontal fire. Derived from French, it literally suggests something 'threaded' like beads on a string. Today the term appears chiefly in architecture, art history, and historical writing about fortifications and warfare, lending any description a note of precision and formality. Knowing enfilade lets you describe both a corridor of connected rooms and a devastating tactical advantage with the same elegant word.
An arrangement of rooms, doors, or windows along a single axis forming an unbroken view; or gunfire directed along the length of an enemy's position.
"The enfilade of reception rooms gave the ambassador's residence its celebrated sense of scale."
The architectural sense is the dominant one in contemporary English.
To direct gunfire along the length of a line, position, or formation; occasionally, to arrange rooms or openings in a straight axis.
"The battery was sited to enfilade the entire ridge road."
The standard plural is regular. In the military sense the singular is often used as a mass noun ('in enfilade').
"The palace plan showed several enfilades running the full depth of the building."
In the palace of Versailles, architects deliberately arranged rooms 'in enfilade' so that from one spot a visitor could gaze through an entire suite of doorways — a trick of perspective designed to make power look infinite.

Etymology of enfilade
Enfilade comes from French enfilade, from enfiler, meaning 'to thread on a string' or 'to run through', formed from the prefix en- plus fil, meaning 'thread'. The underlying image is of objects strung in a line like beads on a thread, whether rooms in a palace or targets along a line of fire. It entered English in the late 17th century, during a period when French architectural and military terminology was widely adopted. It shares this root with words such as file, filament, and profile, all ultimately tracing back to the Latin filum, meaning thread.
How enfilade is actually used
In modern usage the word is most common in architecture, art history, and heritage writing, where it carries connotations of grandeur and formal design. The military sense is largely historical or technical. It is a somewhat learned or specialist word rather than everyday vocabulary.
Easily confused with enfilade
A defile is a narrow mountain pass (from the same root 'fil' meaning thread), while an enfilade is either an architectural alignment of rooms or military fire raked down a line.
