LaPlante
A French surname meaning “the plant” or, in some dialect explanations, “young vine.”
The #4,896 most common surname in the United States (2010 Census) — about 1 in every 42,911 Americans shares it.
Etymology
This surname is usually explained as a French descriptive or topographic name from la plante, meaning “the plant.” In the excerpted source, a southern French/Occitan note also gives a related sense, “young vine,” which fits an agricultural nickname or field-name origin. The form is built with the definite article la plus a noun, a common pattern in French surnames.
History
LaPlante is found in French-speaking regions and later in North America, especially among French-Canadian families. The capitalized internal -P- spelling is a modern Anglicized convention; older records often show forms like Laplante or La Plante. Because surnames of this type often began as nicknames tied to land, crops, or local features, the exact first application is not always recoverable.
