Etymology
The word 'accelerant' is a modern scientific term built directly from Latin components. Its core is the Latin root 'celer', meaning "swift", which can be traced back to the Proto-Indo-European root kel- meaning "to drive, set in motion". The prefix 'ac-' is an assimilated form of 'ad-' ("to"), intensifying the action of the root. The suffix '-ant' forms an agent noun. Thus, the literal construction "that which acts toward swiftness" perfectly captures its modern meaning as a substance that speeds up a process, most commonly used in the context of fire to denote a material that increases the rate of combustion.

- ac: Latin prefix (ad-), meaning "to, toward, near". Assimilated to 'ac-' before 'c'.
- celer: Latin root (celer-), meaning "swift, quick, fast".
- ant: Latin suffix (-antem), forming agent nouns meaning "a person or thing that performs an action".
