What you eat is named the same as it was in Rome. What you break the soil with is named the same as it was among the Slavs. Between the two word-layers sits a tool that arrived centuries after the language had already set.
Seven words describe what reaches the table: pâine (bread), grâu (wheat), făină (flour), apă (water), sare (salt), a semăna (to sow), a secera (to reap). All trace their ancestry straight to Latin, even if their exact form and sense have changed over nearly two thousand years. The heavy tool that opens the furrow to grow that wheat, plug, the plow, has a different origin: it comes from Slavic. So do brazdă (furrow), plaz (sole) and osie (axle); cormană (moldboard) comes from Hungarian.
This isn't only a coincidence of sound: it's most likely a chronology, too. The etymologies themselves clearly show which words trace to Latin and which to Slavic or Hungarian roots. The explanation below, of when and why the heavy plow came into use, is a historical interpretation, not a fact the etymologies establish directly. The most commonly cited hypothesis: Romanian formed its vocabulary for food using Roman words, at a time when the plow actually used on this land was simpler, closer to the Roman aratrum. Intense contact with Slavic populations, conventionally placed in the 6th–9th centuries, would then have brought a new tool to the village, the heavy plow with wheels and an asymmetric moldboard, and its name along with it.
The hard core of subsistence was never replaced. Even the basic verbs of fieldwork, to sow, to reap, stayed Latin.
Touch each word in the diagram. Four are direct borrowings from Slavic or Hungarian: moldboard, sole, drawbar, axle. Three are Romanian formations built on older, borrowed roots: share, beam, wheel. One, handles, is a direct Latin inheritance. The ninth word, furrow, isn't a part of the plow at all: it's the result of its work, the strip of turned earth, and it too is a Slavic word.

The words for work on the estate follow the same pattern. The vocabulary of feudal obligation, who works for whom and what they owe, is in turn mostly Slavic or Hungarian: the institutions it names are later than the language's original Latin core.
One plausible explanation comes from the history of the technology itself. Historian Lynn White Jr. argued, in Medieval Technology and Social Change (1962), that the light Roman-type plow (aratrum), suited to Mediterranean soils, scratches the furrow without turning it, while the heavy wheeled plow, with its asymmetric moldboard able to cut and actually turn the soil, spread through northern and eastern Europe precisely onto heavier ground. White's thesis concerns Europe broadly, not the Romanian case specifically. Applied here, it stays a plausible reason the tool's name might have arrived with the technique, after the food vocabulary had already settled in Latin, not direct proof of that order of events.
You can eat for a thousand years in Roman words and still break the ground with a tool whose name neither Rome nor your Latin ancestors ever heard.
Every etymology shown here comes from DEX ’09 (the Romanian Explanatory Dictionary, 2009 edition), consulted through the public API of dexonline.ro, which preserves the etymology line exactly as it appears at the end of the academic entry (e.g. "– Din sl. plugŭ," from Slavic). Words with disputed, unknown ("et. nec."), or unclear dual etymology were excluded from the main diagram, for instance hambar, which DEX attributes jointly to Hungarian and Bulgarian. The "native Romanian" classification marks words formed within Romanian from a borrowed or inherited root with a Romanian suffix, not direct borrowings themselves. The historical explanation in the previous section is Lynn White Jr.'s thesis, applied here to the Romanian case, not a conclusion that follows directly from the etymologies above.
