Coordinated structures often contain material that belongs equally to two or more members. Esperanto can state that shared material once: one subject can govern several verbs, one object can complete several verbs, and one preposition can introduce coordinated complements. This economy is standard, but it works only when the omitted relationship is grammatically identical and immediately recoverable.
For the basic mechanics of joining complete subjects, objects, and complements, begin with coordination of phrases. This page concentrates on material that is expressed once but understood in more than one coordinated member.
One subject shared by coordinated predicates
When the same subject performs several actions, mention it once and coordinate the predicates. This is neutral in conversation and writing.
Nora malfermis la pordon, eniris kaj ŝaltis la lumon.
Nora opened the door, went in, and turned on the light.
The subject Nora belongs to malfermis, eniris, and ŝaltis. Repeating Nora or ŝi before every verb is grammatical, but it suggests a new contrast or sounds needlessly heavy.
La teknikisto kontrolis la kablojn kaj poste restartigis la servilon.
The technician checked the cables and then restarted the server.
Ĉu vi legis kaj subskribis la kontrakton?
Did you read and sign the contract?
In the question, vi is shared, and la kontrakton is also understood with both transitive verbs. The compact sentence is clear because people can both read a contract and sign it.
If the subjects differ, express the change:
Nora malfermis la pordon, kaj Leo portis la skatolojn enen.
Nora opened the door, and Leo carried the boxes inside.
Leaving out Leo would assign both actions to Nora. Coordination never overrides the ordinary rule that an expressed subject continues across coordinated predicates unless another subject appears.
One object shared by several verbs
A following object may complete each of several coordinated verbs:
Ni redaktis, tradukis kaj publikigis la gvidilon en tri semajnoj.
We edited, translated, and published the guide in three weeks.
Each expansion is grammatical: redaktis la gvidilon, tradukis la gvidilon, publikigis la gvidilon. The object appears once at the end, where new or heavy information naturally belongs.
Different subjects can also share a final object:
Lina presis, Marko subskribis, kaj mi sendis la kontrakton.
Lina printed, Marko signed, and I sent the contract.
This pattern is accepted standard Esperanto. It asks the reader to hold the incomplete verbs until the common object arrives, so it works best with short parallel clauses and a predictable object. In legal or technical (formal) prose, repeating the object may be safer if each action has different conditions.
The verbs must assign the shared phrase the same role. English sometimes coordinates verbs with different frames and lets one complement appear to serve both. Esperanto should expose the difference:
Ŝi serĉis la dosieron kaj demandis min pri ĝi.
She looked for the file and asked me about it.
Serĉi takes a direct object, while demandi iun pri io takes a person as object and the topic with pri. A single unmarked la dosieron cannot naturally satisfy both frames.
Shared verbs and controlled gapping
When two coordinated clauses have different subjects but the same verb, the second verb can be omitted if the parallel is unmistakable.
Petro venis per buso, kaj Karla per biciklo.
Petro came by bus, and Karla by bicycle.
The second part means Karla venis per biciklo. Keeping Karla is essential because its subject differs from the first clause’s subject.
— Kiu mendis kion? — Mi mendis la supon; Eva, la salaton.
— Who ordered what? — I ordered the soup; Eva, the salad.
This compressed answer is natural in (informal) dialogue because the question supplies mendis. In an isolated written sentence, Mi mendis supon, kaj Eva mendis la salaton is clearer.
When the subject is the same, do not retain it while deleting only the repeated main verb:
Petro manĝis la supon kaj poste la kukon.
Petro ate the soup and then the cake.
Standard usage omits both the second manĝis and its same-reference subject. Petro manĝis la supon, kaj poste li la kukon is not the ordinary pattern; either say ...kaj poste la kukon or repeat the verb ...kaj poste li manĝis la kukon.
Sharing a preposition or other role marker
One preposition may govern coordinated complements that have the same relation.
Ni vojaĝis per trajno kaj buso ĝis la marbordo.
We traveled by train and bus to the coast.
The single per governs both trajno and buso. Repeating it—per trajno kaj per buso—is equally standard and gives each means separate prominence.
La kurso estas por komencantoj kaj por homoj, kiuj volas refreŝigi sian Esperanton.
The course is for beginners and for people who want to refresh their Esperanto.
The repeated por makes the boundary clear before a long second phrase. End weight favors putting that longer member last.
Do not let one preposition appear to govern a member with a different relation:
Ni veturis de Liono ĝis Parizo kaj poste al Bruselo.
We traveled from Lyon to Paris and then to Brussels.
The source, endpoint, and next destination require de, ĝis, and al. “Sharing” de would change the structure rather than shorten it.
Shared clause frames
A main verb can take two coordinated subordinate clauses. Repeating the introducer clarifies that both clauses have the same role.
La kuracisto diris, ke mi ripozu kaj ke mi trinku pli da akvo.
The doctor said that I should rest and that I should drink more water.
This contains two coordinated ke clauses. Because each has its own explicit mi, the parallel boundary is obvious. A more compact sentence is also possible:
La kuracisto diris, ke mi ripozu kaj trinku pli da akvo.
The doctor said that I should rest and drink more water.
Now one ke clause contains two coordinated verbs with a shared subject. The meanings are nearly identical, but the grammatical packaging differs.
Keep a subject in each separately introduced subordinate clause. Ŝi diris, ke ŝi venos kaj ke alportos deserton is not standard: after the second ke, the new subordinate clause needs ŝi. Either repeat ŝi or omit the second ke.
Modifier scope across coordination
A modifier before the first member may or may not be intended to cover the second. Malnovaj libroj kaj revuoj can mean “old books and magazines” or “old books and unspecified magazines.” Agreement does not settle the scope because both nouns are plural.
Ni kolektas malnovajn librojn kaj malnovajn revuojn.
We collect old books and old magazines.
Ni kolektas malnovajn librojn kaj lokajn revuojn.
We collect old books and local magazines.
The minimal contrast shows why repetition is useful. A shared modifier is economical only when its wide scope is obvious. The same applies to determiners: la direktoro kaj kasisto may describe one person with two roles, while la direktoro kaj la kasisto clearly presents two referents.
Word order and the shared unit
The normal SVO baseline makes shared relations easiest to recover: subject first, coordinated predicates next, and a shared object afterward. Case marking permits fronting the complete shared object:
La kontrakton Lina presis, Marko subskribis, kaj mi sendis.
As for the contract, Lina printed it, Marko signed it, and I sent it.
This object-first pattern is grammatical, but it is strongly topic-marked and heavier than the version with la kontrakton at the end. It works when the contract is already the explicit topic. It is a poor neutral opening.
Do not separate a modifier from the shared noun to force a special order. La kontrakton Lina presis longan, Marko subskribis... makes longan compete with a predicative reading and overloads the coordination. Keep the object phrase intact or repeat what is necessary.
Common Mistakes
Sharing an object across incompatible verb frames
❌ Ŝi serĉis kaj demandis la dosieron.
Incorrect for the intended meaning — serĉi and demandi do not assign the file the same role.
✅ Ŝi serĉis la ŝlosilojn kaj demandis Leon pri ili.
She looked for the keys and asked Leo about them.
Omitting a changed subject
❌ Nora malfermis la pordon kaj portis la skatolojn.
Incorrect for the intended change of actor — this says that Nora performed both actions.
✅ Nora malfermis la pordon, kaj Leo portis la skatolojn.
Nora opened the door, and Leo carried the boxes.
Dropping the subject after a repeated ke
❌ Ŝi diris, ke ŝi venos kaj ke alportos deserton.
Incorrect — the second separately introduced subordinate clause needs a subject.
✅ Ŝi diris, ke ŝi venos kaj ke ŝi alportos deserton.
She said that she would come and that she would bring dessert.
Assuming a modifier has automatic wide scope
⚠️ La vendejo ofertas rabatitajn librojn kaj ludojn.
Ambiguous — it is unclear whether the games are discounted too.
✅ La vendejo ofertas rabatitajn librojn kaj rabatitajn ludojn.
The shop offers discounted books and discounted games.
Key Takeaways
- Shared material must have the same grammatical role and meaning in every coordinated member.
- A subject, final object, verb, preposition, or clause frame may be stated once when recovery is immediate.
- Different subjects must remain visible; separately introduced subordinate clauses normally retain their subjects.
- Modifier sharing often creates scope ambiguity, so repeat the modifier when its reach matters.
- Neutral SVO and end placement of a shared object are normally clearer than strongly fronted alternatives.
