IPA: /ˈtæɡənt/
KK: /ˈtæɡənt/
A small substance added to a product to show where it was made or to help identify it.
The manufacturer included a taggant in the explosives to ensure they could be traced back to their source.
Taggant is derived from the word 'tag' (from Middle English 'tagge', meaning a label or marker) and the suffix '-ant' (meaning one who or that which). The term 'taggant' refers to a substance or marker that is used to identify or label something.
Think of a 'tag' as a label that helps identify something, and '-ant' means it is something that does the action — so a taggant is something that labels or identifies.
