What does decollate mean?
To decollate means, most literally, to behead — to cut off the head of a person or animal. The word derives from the Latin decollare, formed from de- ('off') and collum ('neck'), making it a close cousin of words like collar and decolletage. In modern English it is rare and decidedly formal, encountered chiefly in historical accounts of executions, where phrases such as 'decollated by order of the crown' lend a clinical, Latinate tone to a grim act. Separately, decollate survives as technical vocabulary in printing and data processing, where it refers to separating individual sheets or sets from a continuous web or joined stack — essentially the reverse of collating. This second sense arose by analogy with 'collate', which means to assemble pages in order. Because both meanings are specialised and infrequent, decollate is best treated as a learned or professional term rather than part of everyday speech.

The word for cutting off heads comes straight from the Latin word for neck — the same root that gives us 'collar'.

Etymology of decollate
Decollate comes from the Latin decollare, meaning 'to behead', built on de- ('off') and collum ('neck'). It entered English around the early 17th century, largely through historical and legal accounts of capital punishment. Its relative rarity kept it close to its original sense, though a distinct printing-industry sense later developed by analogy with 'collate'. Words such as 'collar' and 'decolletage' share the same Latin root referring to the neck.
