What does amatol mean?
Amatol is a military high explosive made by mixing ammonium nitrate with TNT (trinitrotoluene). Developed during the First World War, when TNT supplies were strained, it allowed nations to stretch scarce TNT by blending it with the cheaper, more abundant ammonium nitrate. Common formulations included 80/20 and 50/50 mixtures of ammonium nitrate to TNT; the higher the TNT content, the more powerful the blast. Amatol filled countless artillery shells, aerial bombs, and depth charges during both World Wars, making it one of the most widely used explosives of the twentieth century. The word itself is a portmanteau coined directly from its two ingredients. Today amatol appears almost exclusively in historical and technical contexts — ordnance manuals, military histories, and accounts of munitions manufacturing — rather than in everyday speech, but it remains a significant term for anyone studying the industrial warfare of the modern era.
nounAn explosive mixture of ammonium nitrate and TNT (trinitrotoluene), used extensively in military shells and bombs, especially during the First and Second World Wars.
- A military high explosive consisting of a mixture of ammonium nitrate and TNT, typically in ratios such as 80/20 or 50/50.
"The wartime factory produced tons of amatol each week for filling artillery shells."
"Engineers packed the depth charges with amatol to maximise their underwater blast."
"By 1917, shortages of TNT had forced British munitions plants to rely increasingly on amatol for shell fillings."
Rarely pluralised; the plural appears only when referring to different varieties or batches of the explosive.
"The report compared the performance of several amatols tested at the proving ground."
Named by simply fusing 'ammonium nitrate' and 'TNT' into one word, amatol was the workhorse explosive that filled millions of shells in both World Wars.

Etymology of amatol
The word amatol is a twentieth-century English coinage formed as a blend of 'ammonium nitrate' and 'TNT' (trinitrotoluene), the two substances that make up the explosive. It arose during the First World War among munitions specialists who needed a convenient name for the new mixture. As a modern compound name, it has no ancient roots or foreign-language cognates, though its components trace back to 'ammonium' (from sal ammoniac) and 'toluene' (from tolu balsam).
How amatol is actually used
Amatol is a technical and historical term, encountered mainly in military history, ordnance literature, and period accounts of the World Wars; it is not part of everyday vocabulary.
