The word 'zinc' entered English in the 17th century from the German 'Zink'. The German term likely derives from 'Zinke', meaning 'point' or 'prong', a reference to the jagged, pointed form in which the metal often solidified in early smelting processes. This name was possibly influenced by the similar-sounding but unrelated Persian word 'sing', meaning 'stone'. The journey of the word reflects the metal's practical discovery and characterization in European metallurgy, moving from a descriptive term for its physical appearance to its established chemical identity.

The word 'zinc' is a simplex loanword. It does not contain separable morphemes in modern English.
