   • 1839, J. C. Loudon, The Gardener's Magazine, page 420:

     I have been invited to see the garden of Baron Zanoli, situated on the high road from Monza to Milan, in which I am told there are fine exotic trees and shrubs, and especially a rich collection of pinuses.

   • 1853, George Greenwood, The tree-lifter, page 265:

     As the generality of pinuses grow by nature into magnificent and gigantic forest-trees, they should, I think, be planted in our parks as well as in our flower-gardens, shrubberies, and lawns.

Of disputed origin, with multiple theories proposed:[1]

• From the same origin as Ancient Greek πῐ́νᾰξ (pínax, “wooden board, plank”).
• From the same origin as Ancient Greek πίτῠς (pítus, “pine tree”) and Albanian pishë (“id”), which is generally reconstructed as Proto-Indo-European *pī́ts.
• Related to pix (“pitch, tar”), itself generally considered of the same origin as the second etymology above.

See also Sanskrit पितु (pitu, “sap, juice, resin”).

• (Classical) IPA^(key): /ˈpiː.nus/, [ˈpiːnʊs̠]
• (modern Italianate Ecclesiastical) IPA^(key): /ˈpi.nus/, [ˈpiːnus]
