Etymology
It is Middle English oke, ook, inherited from Old English āc (“oak tree”),[2][3][4] partly also from Old Norse eik,[3] from Proto-Germanic *aiks,[3][5] source also of Old Saxon ēk, Dutch eik and German Eiche,[2][3] with no certain cognates outside Germanic;[3][5] Word Origins and MWU relate it to Latin aesculus (“a kind of oak”) and Greek aigilōps.[6][4]
Earliest recorded meaning
The tree: 749 in the OED, about 700 in Barnhart.[7][2]
Semantic evolution
The usual Indo-European word for oak, *deru-, became English tree, which Etymonline takes to reflect the importance of the oak to the ancient Indo-Europeans.[3] As Iceland had no oaks, Old Norse eik came to mean any tree there.[3] English Bibles use oak for Hebrew ēlāh, probably the terebinth (1382).[7][3] Oak timber, especially for ships, is Old English,[7] hence Garrick's Heart of oak are our ships.[6] Other trees resembling oaks were called oak from 1551, including Australian casuarinas from 1802.[7]
