Quantity: iom, multe, kelkaj and the da Rule
Every language needs a way to say some, a few, a lot and too much, and most of them make a quiet mess of it - English of alone covers quantity (a cup of tea), possession (the house of my father), material (a heart of gold) and about nine other relations, and nobody notices until they learn a language that refuses to blur them. Esperanto refuses. It has a short, regular set of quantity words, and it has a preposition, da, whose only job in the entire language is the quantity link. This article covers both - and versus de is the centrepiece, because it is the one place the topic actually bites.
The quantity words
The working set is small:
iom - some, a bit:
(some time)kelkaj - a few:
(a few apples)multaj /
- many / much:,
- little, not much:(little money)tro - too much:
(too much work)sufiĉe - enough:
(enough time)tuta - whole:
(the whole day)
Notice the split hiding in the list. Some of these are adjectives - , , - and they sit directly on the noun and agree with it, exactly per nouns and adjectives: , , . The others are adverbs or particles - , , , - and they cannot touch the noun directly. They need a link. The link is .
The da rule
A quantity expression links to the substance it measures with .
- a glass of water
- a lot of people
- some time
- a kilo of bread
- a cup of tea
The shape is always the same: quantity on the left, substance on the right, between them. The left side can be a measure noun (glaso, taso, botelo, peco, amaso), a quantity adverb (, , , ), or the question word kiom - how much, the ki- cell of the quantity row in the correlatives table: ? The right side is the stuff being measured, and it stays bare - no article, no -n (the phrase as a whole can be an object, but the noun after never takes -n: ).
English of does this job too, which lulls anglophones into thinking is just of in a hat. It is not, and the next section is why.
Never da before la
Here is the rule that sorts real Esperantists from translation-by-reflex:
never stands before . Or before , or , or any word that identifies. The moment the substance becomes a specific, identified thing, takes over:
- a glass of wine
- a glass of the wine
The logic is genuinely satisfying once it clicks. introduces a substance being measured - wine in general, as stuff. La introduces a thing already identified - that wine, the one on the table. You cannot measure out "wine as stuff" and point at "the specific wine" in the same breath; the two jobs cancel. So when you take a glass from an identified bottle, the relation is no longer pure quantity but a portion of a particular thing, and the portion-of-a-particular-thing preposition is : (much of the wine), (some of that cake).
Mechanical test, no philosophy required: if the next word is , , a possessive or a name, is wrong. Always.
da vs de: the minimal pairs
Strip the article away and the two prepositions still contrast - this is the pair to memorise:
- a glassful of wine. The glass is measuring; the wine is the point.
- a wine glass. The glass is the point; the wine is a mere association - the kind of glass it is, probably empty.
Quantity versus association, in two letters. A few more to calibrate on:
- a bottle of milk (a bottleful, you can drink it)
- a milk bottle (the container for milk)
- a heap of work (a lot of work)
- the door of the house (no quantity anywhere; pure)
And everything English of does that is not measuring - possession ( ), origin, authorship, material - is territory, full stop. is a specialist; when in doubt, is the general-purpose word and the safer guess.
Numbers take no da
One more boundary. A plain numeral is not a quantity - it behaves like an adjective, sitting straight on the noun:
- three apples. Never.
- ten people.
The line runs between word classes, not meanings. Numerals (tri, dek, cent) attach directly; quantity nouns take even when they name numbers - (a million people), dekduo (a dozen eggs) - because and dekduo are nouns and need the link. Same idea, different grammar, and the numbers article has the full inventory.
Which also explains the / doublet from the word list: (adjective, agreeing, no ) and (adverb, linked by ) are both correct and interchangeable. The adverb-plus- version is the idiomatic default in speech; the adjective version reminds you the agreement machinery from nouns and adjectives still applies to any quantity word wearing -a: .
What to take away
- The quantity words:
,,/,,,,. Adjectives among them agree; adverbs link with. - The
rule: quantity ++ bare substance.?. - Never
takes over - - The minimal pair:
- Plain numerals take no
: is a plural adjective and agrees like one:
