Gael. suith, Ir. suth.] A black substance formed by combustion, or disengaged from fuel in the process of combustion, which rises in fine particles, and adheres to the sides of the chimney or pipe conveying the smoke; strictly, the fine powder, consisting chiefly of carbon, which colors smoke, and which is the result of imperfect combustion. See Smoke.

Douglas Harper's Etymology Dictionary

Old English sot "soot," from Proto-Germanic *sotam "soot" (cognates: Old Norse sot, Old Dutch soet, North Frisian sutt), literally "what settles," from PIE *sod-o- (cognates: Old Church Slavonic sažda, Lithuanian suodžiai, Old Irish suide, Breton huzel "soot"), suffixed form of root *sed- (1) "to sit" (see sedentary).


n. Fine black or dull brown particles of amorphous carbon and tar, produced by the incomplete combustion of coal, oil etc. vb. (context transitive English) To cover or dress with soot.

  1. n. a black colloidal substance consisting wholly or principally of amorphous carbon and used to make pigments and ink [syn: carbon black, lampblack, smut]

  2. v. coat with soot


Soot is a mass of impure carbon particles resulting from the incomplete combustion of hydrocarbons. It is more properly restricted to the product of the gas-phase combustion process but is commonly extended to include the residual pyrolysed fuel particles such as coal, cenospheres, charred wood, and petroleum coke that may become airborne during pyrolysis and that are more properly identified as cokes or chars.

Soot is theorized to be the second-largest cause of global warming.

Soot (software)

In static program analysis, Soot is a language manipulation and optimization framework consisting of intermediate languages for the Java programming language. It has been developed by the Sable Research Group at McGill University known for its SableVM, a Java virtual machine and the AspectBench Compiler, an open research compiler for AspectJ. In 2010, two research papers on Soot ( and ) were selected as IBM CASCON First Decade High Impact Papers among 12 other papers from the 425 entries.

Soot provides four intermediate representations for use through its API for other analysis programs to access and build upon:

  • Baf: a near bytecode representation.
  • Jimple: a simplified version of Java source code that has a maximum of three components per statement.
  • Shimple: an SSA variation of Jimple (similar to GIMPLE).
  • Grimp: an aggregated version of Jimple suitable for decompilation and code inspection.

The current Soot software release also contains detailed program analyses that can be used out-of-the-box, such as context-sensitive flow-insensitive points-to analysis, call-graph analysis and domination analysis (answering the question "must event a follow event b?"). It also has a decompiler called dava.

Soot is free software available under the GNU Lesser General Public License (LGPL).
