Antaŭ

Antaŭ organizes space and time with the same basic image: one thing comes on the front or earlier side of another. It can mean “in front of,” “before” in a sequence, or “before/ago” in time. The reference point after antaŭ normally has no -n; directional -n appears only when real movement into a front position is being expressed.

Physical position in front of something

Spatial antaŭ places one entity on the front side of a reference object or person:

What counts as “front” depends on perspective. A person or animal has a natural front at the face. A building normally has a socially recognized front or main entrance. With an object that lacks an obvious front, context or the observer's viewpoint supplies one.

Antaŭ does not itself say that two things touch or that the distance is small. It identifies the front-side relation. Apud gives side proximity, while ĉe gives general proximity without specifying front, back, or side.

Static position versus movement into position

In a static description, use the nominative after antaŭ:

When something moves from elsewhere into a position in front of the reference point, directional -n can make that endpoint explicit:

The broader conditions for this contrast are covered under Prepositions with Optional Directional -n.

The packages end up in a new front position, so pordon is possible. In many placement sentences, speakers also use antaŭ la pordo when another understood surface or location is treated as the actual endpoint. The safest learner distinction is semantic: use -n only when you deliberately mark movement into the antaŭ-location, never merely because the main verb describes motion.

Although marŝis is a motion verb, la grupo stays nominative because she remains in front of it while moving. Motion alone does not trigger directional -n.

Position in an order or sequence

The front–back image extends naturally to ordered lists and queues:

This sequential meaning is not about physical closeness. A chapter can come before another chapter, one agenda item before another, or one competitor before another in a ranking.

Antaŭ ĉio is a conventional extension meaning “above all” or “first of all”: the named consideration receives first place in an order of importance.

Earlier than a time or event

Temporal antaŭ places an event earlier than its reference point. Its opposite is post.

The complement can name a date, time, event, or action understood as a temporal landmark. Antaŭ la koncerto means before the concert occurred, not necessarily physically in front of it.

With a duration measured backward from now, antaŭ + quantity corresponds to English “ago”:

No accusative appears on tri jaroj, because it is the complement of the preposition. To measure the gap before an explicitly named event, place an accusative measure before the prepositional phrase:

Here du semajnojn is an accusative measure of temporal distance; la festivalo remains the nominative complement of antaŭ. The two endings perform different jobs.

Clock time: antaŭ versus je

Je la oka gives the event's clock time. Antaŭ la oka places it earlier than eight:

For relative clock expressions, a measure can precede antaŭ: dek minutojn antaŭ la tria means 2:50. Do not use je when “earlier than” is part of the message; je identifies a point, while antaŭ orders one time relative to another.

Antaŭ ol with a clause or infinitive

Antaŭ is a preposition, not by itself a clause introducer. Use antaŭ ol before a finite clause or an infinitive:

With a noun phrase, no ol is needed: antaŭ via foriro, antaŭ la respondo. With a finite verb or infinitive, antaŭ ol makes the temporal comparison explicit. English “before you leave” therefore cannot be copied as antaŭ vi foriros.

When the infinitive's subject is understood from the main clause, antaŭ ol respondi, ŝi... is compact and clear. If subjects differ, use a finite clause: antaŭ ol la gastoj alvenos, ni pretigos la tablon.

Antaŭe, antaŭen, and antaŭa

When no complement follows, Esperanto uses derived forms:

• antaŭe — earlier, previously, or ahead in a sequence;
• antaŭen — forward, toward the front;
• antaŭa — front, previous, earlier.

Compounds such as antaŭpordo “front door,” antaŭĉambro “anteroom,” and antaŭvidi “foresee” extend the same spatial or prior-time image. Their conventional meanings should still be learned individually.

Antaŭ versus malantaŭ and post

For physical space, malantaŭ is the opposite of antaŭ: antaŭ la domo / malantaŭ la domo. For time and sequence, the opposite is post: antaŭ la kunveno / post la kunveno. Malantaŭ la kunveno would describe a physical location behind a meeting only in an unusual metaphor; it is not the ordinary way to mean “after the meeting.”

This asymmetry must be memorized. Esperanto's regular mal- gives the opposite spatial side, but the language has conventionalized post for later time and later sequence.

Norm, usage, and register

The spatial, sequential, and temporal meanings are foundational and common in every register. Directional -n after antaŭ is also standard when movement into the front position is genuinely marked. Actual usage varies when a placement verb allows speakers to construe either the front position or an understood surface as the endpoint; both analyses can be legitimate.

In neutral prose, choose the form that makes the contrast visible: static antaŭ la pordo, directional antaŭ la pordon, temporal antaŭ la kunveno, and clausal antaŭ ol ni komencos.

Common Mistakes

Adding -n in a static location

Using antaŭ alone before a clause

Copying English “ago” with antaŭe

Using the spatial opposite for later time

Key Takeaways

• Antaŭ marks the front side, an earlier place in an order, or an earlier time.
• Its ordinary complement has no -n; directional -n is meaningful only for movement into an antaŭ-position.
• Antaŭ tri tagoj means “three days ago”; tri tagojn antaŭ la evento measures a gap before an event.
• Use antaŭ ol before clauses and infinitives.
• The spatial opposite is malantaŭ, but the temporal and sequential opposite is post.
