English more, less, fewer, and most can compare a quality, an amount, a count, a frequency, or an additional item. Esperanto makes the intended scale visible. Pli longa raises a degree of length; pli da tempo raises an amount; pli multaj partoprenantoj raises a count; plia tago adds another unit. Choosing among these patterns is the heart of accurate quantity comparison.
First decide: degree or quantity
Direct pli/malpli + adjective or adverb compares intensity or degree.
La nova botelo estas pli granda ol la malnova.
The new bottle is larger than the old one.
La nova botelo enhavas pli da akvo ol la malnova.
The new bottle contains more water than the old one.
The first sentence compares bottle size; the second compares the quantity of water. English uses more in expressions such as more useful and more water, but Esperanto separates pli utila from pli da akvo.
Mi bezonas malpli pezan valizon, sed pli da spaco interne.
I need a lighter suitcase but more space inside.
Malpli pezan lowers the degree of weight. Pli da spaco increases an amount. This decision must be made before translating English more or less.
Pli da and malpli da with nouns
Use pli da + noun for a greater amount and malpli da + noun for a smaller amount. The pattern works with mass nouns and countable plurals.
Ni bezonos pli da faruno kaj malpli da sukero.
We will need more flour and less sugar.
Ĉi-jare la festivalo ricevis pli da proponoj ol pasintjare.
This year the festival received more proposals than last year.
La nova proceduro postulas malpli da dokumentoj.
The new procedure requires fewer documents.
English distinguishes less sugar from fewer documents. Esperanto uses the same quantitative malpli da for both. The noun after da names what the quantity consists of.
Because da is a preposition, the following noun does not receive accusative -n even when the entire quantity expression functions as an object:
Mi trinkis pli da akvo dum la varma posttagmezo.
I drank more water during the hot afternoon.
Do not write pli da akvon. The invariant quantity word pli functions as the head of the object-like quantity expression; akvo belongs to the da phrase. See the preposition da for the full syntax of quantity phrases.
Count explicitly with pli multaj
With countable plural nouns, pli multaj and malpli multaj provide an adjective-based alternative. They emphasize the number of individual members and agree normally.
Pli multaj najbaroj partoprenis en la dua kunveno.
More neighbors took part in the second meeting.
Ni invitis malpli multajn gastojn ĉi-foje.
We invited fewer guests this time.
In the first sentence, pli multaj najbaroj is a plural subject. In the second, malpli multajn gastojn is plural accusative. Compare the equally standard quantity phrases:
En la dua kunveno partoprenis pli da najbaroj.
More neighbors took part in the second meeting.
Ni invitis malpli da gastoj ĉi-foje.
We invited fewer guests this time.
The da construction treats the referents as a quantity; multaj directly describes a plural set as numerous. The difference is usually one of packaging and focus, not a difference in factual count. With mass nouns such as akvo, use pli da akvo, not pli multaj akvoj, unless you genuinely mean multiple kinds or servings of water.
Equal quantities: tiom ... kiom
The -om correlatives compare quantity: tiom points to the amount being stated, and kiom introduces the matching amount or asks “how much/many?”
Ni preparis tiom da seĝoj, kiom da homoj aliĝis.
We prepared as many chairs as people registered.
La projekto ne kostis tiom, kiom ni antaŭvidis.
The project did not cost as much as we predicted.
Prenu tiom da pano, kiom vi volas.
Take as much bread as you want.
In the first example, repeating da after kiom is useful because an expressed noun follows: kiom da homoj. In the second, the measured amount is understood, so tiom and kiom stand alone.
Tiel ... kiel compares degree or manner; tiom ... kiom compares amount. With multe, both systems can overlap—tiel multe kiel and tiom, kiom—but tiom da + noun is the clearest default for a noun quantity.
Ĉu ni havas tiom da baterioj, kiom ni bezonos?
Do we have as many batteries as we will need?
The -om words never take -j or accusative -n. They are invariant table words even when they function as subject or object.
Comparing the amount of an action
With a verb, bare pli or malpli may mean a greater or smaller overall amount of activity. Add an adverb when the precise scale matters.
Ekde Januaro mi pli kuiras kaj malpli mendas manĝaĵojn.
Since January I cook more and order food less.
Mi dormas pli longe sed vekiĝas pli ofte.
I sleep longer but wake up more often.
Post la translokiĝo ni veturas malpli multe.
After moving, we travel less overall.
These sentences compare different scales: total activity, duration, and frequency. English I travel less leaves the scale similarly broad; malpli multe makes overall amount explicit, while malpli ofte would specifically mean fewer occasions and malpli longe shorter duration.
— Ĉu vi nun laboras malpli? — Ne malpli longe, sed malpli ofte vespere.
‘Do you work less now?’ ‘Not for less time, but less often in the evening.’
This short exchange shows why “more/less” cannot always be translated before its scale is understood.
Numerical thresholds: pli ol and malpli ol
Before a number, pli ol means “a number greater than,” and malpli ol means “a number smaller than.” The two words act together as a quantity modifier.
La ekspozicion vizitis pli ol dek mil homoj.
More than ten thousand people visited the exhibition.
La respondo alvenis en malpli ol du horoj.
The reply arrived in less than two hours.
Ni veturis pli ol tricent kilometrojn sen longa paŭzo.
We traveled more than three hundred kilometers without a long break.
Any case or preposition belongs to the full measured phrase. Tricent kilometrojn carries the accusative of extent; en malpli ol du horoj remains inside an en phrase. Ol does not erase those roles.
Do not confuse pli ol kvin libroj “more than five books” with pli da libroj ol revuoj “more books than magazines.” The first sets a numerical threshold; the second compares two quantities of things.
Highest and lowest quantities
Use plej multe da for the greatest amount and malplej multe da for the smallest amount.
El la tri fakoj, la medicina ricevis plej multe da kandidatiĝoj.
Of the three departments, the medical one received the most applications.
La plej malgranda ĉambro bezonas malplej multe da hejtado.
The smallest room needs the least heating.
With a countable plural, la plej multaj + plural noun often means the greatest number or, in context, “most” members of the group:
La plej multaj pasaĝeroj jam aĉetas biletojn per la aplikaĵo.
Most passengers now buy tickets through the app.
This is different from la plej + adjective, which ranks a quality. La plej aktivaj pasaĝeroj selects those highest in activity; la plej multaj pasaĝeroj talks about the numerically largest portion.
The comparison set may be stated with el or supplied by context. Plej multe da remains invariable; multaj in la plej multaj is an adjective and carries plural agreement.
“More” versus “additional”: pli and plia
Quantity comparison does not always equal addition.
Ni bezonas pli da tempo.
We need a greater amount of time.
Ni bezonas plian tagon.
We need one additional day.
Pli da tempo compares the available amount with a lower baseline. Plia tago adds another countable unit. Similarly, pli longaj kunvenoj means meetings of greater duration, while pliaj kunvenoj means additional meetings.
La kliento petis ne pli longan raporton, sed plian ekzemplon.
The client asked not for a longer report, but for an additional example.
Degree modifiers before quantity comparatives
Multe, iom, ankoraŭ, and similar words can show the size of a difference.
La nova deponejo havas multe pli da spaco ol la malnova.
The new warehouse has much more space than the old one.
Ni ricevis iom malpli da plendoj ĉi-monate.
We received slightly fewer complaints this month.
Here the first multe modifies comparative pli; it does not form the noun quantity by itself. Word order keeps the layers clear: multe [pli [da spaco]].
Common Mistakes
1. Putting bare pli directly before a quantity noun
❌ Ni bezonas pli tempo por testi la sistemon.
Incorrect — an amount of a noun normally uses pli da.
✅ Ni bezonas pli da tempo por testi la sistemon.
We need more time to test the system.
2. Adding accusative after da
❌ Ŝi aĉetis pli da legomojn ol mi.
Incorrect — the noun after the preposition da does not take accusative -n.
✅ Ŝi aĉetis pli da legomoj ol mi.
She bought more vegetables than I did.
3. Using tiel da for equal quantity
❌ Ni havas tiel da tempo kiel ili.
Incorrect — amount is expressed with the -om correlatives.
✅ Ni havas tiom da tempo, kiom ili.
We have as much time as they do.
4. Confusing a larger amount with an additional unit
❌ Bonvolu doni al mi pli tason da teo.
Incorrect for ‘another cup’ — pli does not directly mean an additional item.
✅ Bonvolu doni al mi plian tason da teo.
Please give me another cup of tea.
5. Inflecting an invariant quantity word
❌ Ni ricevis pliajn da petoj ĉi-jare.
Incorrect — comparative quantity uses invariant pli da, not adjective pliajn da.
✅ Ni ricevis pli da petoj ĉi-jare.
We received more requests this year.
