Proverb: Kdo šetří, má za tři

Kdo šetří, má za tři is the Czech praise of thrift — the rough equivalent of "a penny saved is a penny earned". Word for word it says "Who saves, has for three": the careful person ends up as well off as if they had three times as much. Five short words carry three patterns worth dissecting: a free-relative kdo that serves as a bare subject, an imperfective verb describing a habit, and the slippery preposition za used here to express value, not place.

Word by word

The free-relative kdo as a bare subject

The first surprise for an English speaker is that kdo ("who") is doing the work of "whoever" — and it is doing it all by itself, with no noun and no article in front of it. In English we cannot say "Who saves has more"; we have to upgrade it to "Whoever saves" or "The one who saves" or "People who save". Czech is perfectly happy to let the bare interrogative pronoun kdo stand as the subject of a generalising clause.

This is called a free relative: kdo opens a clause that, taken whole, names an unspecified person — "anyone who saves" — and that clause is itself the subject of the verb má.

The implied resumptive ten

Many Czech proverbs spell out a second pronoun — ten ("that one") — in the main clause to pick kdo back up: Kdo dřív přijde, ten dřív mele ("first come, first served"). In Kdo šetří, má za tři, that resumptive ten is left out. It is recoverable — you could say Kdo šetří, ten má za tři without changing the meaning — but the proverb drops it for rhythm and bite. The verb má simply takes the whole kdo-clause as its subject.

The wider machinery of these two-part frames is laid out on the ten…který correlative page, and the pronoun kdo itself on the kdo / co page.

Why šetří is imperfective

The verb šetří is the present of šetřit ("to save, to economise"), and it is imperfective — exactly the right choice for a proverb. Thrift is not a single event; it is a habit, a standing disposition. The imperfective present is Czech's tense for ongoing and repeated action, so kdo šetří means "whoever is in the habit of saving", true on any day, of any person. A perfective verb would point at one finished act of saving and ruin the generality.

Šetřit belongs to the -í present class (the prosit type): the third-person singular ends in -í, giving šetří.

Note that šetřit governs different cases depending on meaning: šetřit peníze (accusative) is "to save money up", while šetřit penězi (instrumental) or šetřit na něco is "to be sparing with / save up for". In the proverb it stands alone, intransitive: simply "to be thrifty".

The verb má and the idiom za tři

The main clause is just two words: má za tři. The verb má is the third-person present of mít ("to have"). What it "has" is the punchline: za tři, literally "for three".

Here the preposition za is not doing its usual job. English speakers first meet za as a place word — za domem ("behind the house"), za rohem ("around the corner") — where it takes the instrumental. But za is a two-case preposition, and with the accusative it shifts to expressing price, exchange and equivalence: koupil to za stovku ("he bought it for a hundred"), děkuji za pomoc ("thanks for the help"). In the proverb, za tři with the accusative numeral tři means "to the value of three", "as if three (people / portions / wages)".

So má za tři = "has (as much as) for three" — the thrifty person effectively has triple. The exact noun is deliberately omitted; the numeral tři is used substantively, standing on its own without anything to count.

The two-case behaviour of za (and its siblings na, v, o) is detailed on the na / v / o / za: accusative vs locative page. The substantive use of bare numerals like tři is covered under generic numerals.

How Czechs actually use it

The proverb is a gentle endorsement of being careful with money — pulled out when someone clips coupons, mends instead of replaces, or skips an extravagance. It can be sincere praise of frugality or, said with a wink, a tease about being a little tight-fisted. It contrasts neatly with Komu se nelení, tomu se zelení ("things go green for those who don't slack off") — both reward the diligent, one through thrift, the other through effort.

Common Mistakes

Key Takeaways

• Kdo is a free relative — a bare "whoever / the one who" that serves as the subject of the whole sentence. The resumptive ten is understood but dropped for punch.
• šetří is the imperfective present of šetřit (the -í class), marking thrift as a standing habit, not a one-off act.
• za tři uses za + accusative to mean value/equivalence ("worth of three"), a different sense from the locational za
  • instrumental ("behind").
• The numeral tři stands on its own, used substantively with the counted noun left to the imagination.
