Word History
Etymology

Note:
The form (with voiced stop) and spelling depend on French, where the word first appeared in the 16th-century reports of Brazil ("France Antarctique"): in André de Thevet's Les singularitez de la France antarctique, 1558 (agoutin) and Jean de Léry's Histoire d'un voyage faict en la terre du Bresil, 1578 (agouti); agouti was taken up in the next century by Georg Marcgrave and Willem Piso (Historia naturalis Brasiliae, 1648) and in the 18th century by Linnaeus.
