Terminology
''Cornus'' is the Latin word for the cornel tree, ''
Cornus mas
''Cornus mas'', commonly known as cornel (also the Cornelian cherry, European cornel or Cornelian cherry dogwood), is a species of shrub or small tree in the dogwood genus ''Cornus'' native to Southern Europe and Southwestern Asia.
Description

''.
The name ''cornel'' dates to the 1550s, via German from Middle Latin ''cornolium'', ultimately from the diminutive ''cornuculum'', of ''cornum'', the Latin word for the cornel cherry. ''Cornus'' means "horn",
[Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 121]
presumably applied to the cherry after the example of
κερασός, the Greek word for "cherry", which itself is of pre-Greek origin but reminiscent of
κέρας, the Greek word for "horn".
The name "dog-tree" entered the English vocabulary before 1548, becoming "dogwood" by 1614. Once the name dogwood was affixed to this kind of tree, it soon acquired a secondary name as the Hound's Tree, while the fruits came to be known as "dogberries" or "houndberries" (the latter a name also for the berries of

, alluding to
Hecate's hounds).
The name was explained, from as early as the 16th century itself, as derived from ''
dag'' "skewer",
[Vedel, H., & Lange, J. (1960). ''Trees and Bushes in Wood and Hedgerow''. Metheun & Co. Ltd., London.] as the wood of the tree was said to have been used to make butcher's skewers. This is uncertain, as the form ''*dagwood'' was never attested. It is also possible that the tree was named for its berry, called ''dogberry'' from at least the 1550s, where the implication could be that the quality of the berry is inferior, as it were "fit for a dog".

The name ''
whippletree'', also ''whiffle-tree'', now refers to an element of the traction of a horse-drawn cart linking the drawpole of the cart to the harnesses of the horses in file. In this sense it is first recorded in 1733. This mechanism was usually made from oak or ash (and not from dogwood), and it is unlikely that there is a connection to the name for ''whipple-tree'' for Cornus.
