Anstataŭ means that one person, thing, circumstance, or action takes the role that another would otherwise have had. Its core logic is replacement: not coffee but tea, not driving but walking, not one worker but another. English “instead,” “instead of,” “in place of,” and sometimes “rather than” all overlap with it.
Replacing one noun phrase with another
Place anstataŭ before the rejected alternative:
Anstataŭ kafo mi mendis teon kun citrono.
Instead of coffee, I ordered tea with lemon.
La hotelo proponis pli grandan ĉambron anstataŭ repagi nian monon.
The hotel offered a larger room instead of refunding our money.
In the first sentence, tea fills the drink role that coffee would have filled. In the second, offering another room replaces the possible action of refunding. Anstataŭ therefore carries a built-in contrast with an unrealized or displaced alternative; it does not simply add another option.
After an ordinary noun phrase, the basic form is nominative:
Hodiaŭ Leo laboros anstataŭ sia malsana kolegino.
Today Leo will work instead of his sick colleague.
Here the colleague is the person whose worker-role Leo takes. There is no reason to add -n merely because English says “instead of her.”
Anstataŭ + infinitive
Anstataŭ is one of the established Esperanto prepositions that naturally stands before an infinitive:
This is one of the conventional exceptions described under Infinitives After Prepositions.
Anstataŭ atendi la buson, ni piediru ĝis la centro.
Instead of waiting for the bus, let's walk to the center.
Ŝi kontrolis la fontojn anstataŭ simple dividi la onidiron.
She checked the sources instead of simply sharing the rumor.
The understood subject of the infinitive normally comes from the main clause: ni would wait and walk; ŝi could merely share and instead checked. This makes the construction compact and natural.
Do not insert ol. English “rather than wait” can resemble a comparison, but Esperanto replacement is simply anstataŭ atendi, not anstataŭ ol atendi.
— Ĉu ni mendu picon? — Ne, ni kuiru ion hejme anstataŭ elspezi tiom da mono.
— Shall we order pizza? — No, let's cook something at home instead of spending so much money.
When the alternatives have different subjects
If the replaced action has its own explicit subject, use a finite clause, normally anstataŭ tio, ke...:
Anstataŭ tio, ke vi sola portu ĉiujn skatolojn, ni helpu vin.
Instead of you carrying all the boxes alone, let us help you.
The tio provides a noun-like object for the preposition, and ke introduces the clause. Anstataŭ ke without tio is attested and accepted, including in foundational-era writing, but anstataŭ tio, ke makes the structure more transparent for international readers.
Anstataŭ tio, ke la teamo tuj decidu, la estro petis ankoraŭ unu tagon por pripensi.
Instead of the team deciding immediately, the manager asked for one more day to think.
This is not the same as an infinitive controlled by la estro. The finite clause explicitly assigns deciding to la teamo.
The unusual question of grammatical role
Most prepositions identify a role themselves: al marks a target, pro a cause, per a means. Anstataŭ is unusual because it primarily marks replacement and often leaves the displaced expression's role to context. That can create ambiguity.
Petro telefonis al Sara anstataŭ al Marta.
Petro called Sara instead of Marta.
Repeating al shows that Sara and Marta are alternative addressees. Compare:
Petro telefonis al Sara anstataŭ Marta.
Petro called Sara instead of Marta doing so.
Without the second al, Marta is naturally read as the alternative subject: Marta would have called, but Petro did. Repeating the relevant preposition is therefore not empty repetition when it prevents a role ambiguity.
The accusative can serve the same purpose:
Petro invitis Paŭlon anstataŭ Vilhelmon.
Petro invited Paŭlo instead of Vilhelmo.
Petro invitis Paŭlon anstataŭ Vilhelmo.
Petro, rather than Vilhelmo, invited Paŭlo.
In the first sentence, Vilhelmon is the alternative object. In the second, nominative Vilhelmo is the alternative subject. This role-preserving accusative is an accepted special use around anstataŭ, not a license to put -n after it automatically.
Repeating another preposition for clarity
The same principle applies to destinations, causes, instruments, and sources:
Ni veturis al Gento anstataŭ al Bruselo pro la nuligita kunveno.
We traveled to Ghent instead of Brussels because of the canceled meeting.
Ŝi subskribis per cifereca atestilo anstataŭ per plumo.
She signed with a digital certificate instead of with a pen.
Usually context makes a repeated preposition unnecessary: teo anstataŭ kafo is perfectly clear. Retain it when omitting it would suggest a different grammatical role. Do not insert vague je where al, pro, per, or de states the intended relationship precisely.
Anstataŭ, krom, and por
Anstataŭ replaces; krom adds or excepts. Compare:
Anstataŭ la salato ŝi mendis supon.
Instead of the salad, she ordered soup.
Krom la salato ŝi mendis supon.
In addition to the salad, she ordered soup.
The first order contains soup in place of salad. The second contains both. This is a high-value distinction because English “besides” and “instead” can both organize alternatives but produce opposite totals.
Por marks purpose or intended benefit, not replacement. Mi laboris por Ana means that the work was for Ana's benefit or purpose; mi laboris anstataŭ Ana means Ana did not do the work and I took her role.
Historical texts occasionally use pro with a replacement meaning under Latin influence. Modern neutral Esperanto uses anstataŭ. Treating old pro examples as a current synonym would blur the normal cause-versus-replacement distinction.
Anstataŭe, anstataŭa, and the verbs
When no complement follows, add the ordinary word-class ending:
La trajno ne plu veturis, do ni anstataŭe prenis buson.
The train was no longer running, so we took a bus instead.
Anstataŭe is an independent adverb meaning “instead.” Anstataŭa means replacement or substitute: anstataŭa ŝlosilo, anstataŭa instruisto.
Two related verbs require attention:
- anstataŭi iun/ion — to serve in the place of that person or thing;
- anstataŭigi ion per io alia — to cause one thing to be replaced by another.
Mia kolego anstataŭos min dum mia ferio.
My colleague will substitute for me during my vacation.
La teknikisto anstataŭigis la difektitan diskon per nova disko.
The technician replaced the damaged drive with a new one.
The regular -ig- meaning explains the difference: the technician causes the new disk to take the old disk's role.
Norm, usage, and register
Replacement anstataŭ, the infinitive construction, and independent anstataŭe are foundational and neutral in both (informal) and (formal) Esperanto. Repeating a second preposition and using role-preserving -n are accepted ways to prevent ambiguity. In simple contexts, excessive repetition can sound heavy, so use only as much marking as clarity requires.
The alternatives vice al and elided vic' al have been proposed and are understandable, especially in (literary) wordplay, but they never displaced ordinary anstataŭ. Learners should use the established form.
Common Mistakes
Adding de because English says “instead of”
❌ Mi prenis teon anstataŭ de kafo.
Incorrect — simple replacement takes anstataŭ directly, without de.
✅ Mi prenis teon anstataŭ kafo.
I had tea instead of coffee.
Copying an English -ing form
❌ Anstataŭ plendante, proponu solvon.
Incorrect — after anstataŭ, the alternative action takes the infinitive.
✅ Anstataŭ plendi, proponu solvon.
Instead of complaining, propose a solution.
Losing the repeated role marker
❌ Ni sendis la fakturon al la kliento anstataŭ la librotenisto.
Incorrect for the intended recipient contrast — this says the accountant was the alternative sender.
✅ Ni sendis la fakturon al la kliento anstataŭ al la librotenisto.
We sent the invoice to the client instead of to the accountant.
Confusing anstataŭi and anstataŭigi
❌ La nova presilo anstataŭigis la malnovan.
Incorrect for a simple substitution — anstataŭigi means to cause something else to replace something.
✅ La nova presilo anstataŭis la malnovan.
The new printer replaced the old one.
Key Takeaways
- Anstataŭ marks a displaced alternative whose role another person, thing, or action fills.
- It naturally introduces an infinitive; use anstataŭ tio, ke... when the alternative action has its own subject.
- Repeat a preposition or preserve object -n when the replaced grammatical role would otherwise be ambiguous.
- Krom adds or excepts; anstataŭ replaces.
- Anstataŭe stands alone, anstataŭi means to substitute for, and anstataŭigi means to cause a replacement.
