Understanding One-Word Substitution for Flammable Substances
The question asks for a single word that can replace the phrase "A thing or substance that is liable to catch fire easily". This requires us to find a word that describes something which ignites quickly and easily burns.
Analyzing the Options for Inflammable Substances
Let's examine the given options to determine which one best fits the description of a substance liable to catch fire easily.
- Inaudible: This word describes something that cannot be heard. It is related to sound, not fire or combustion. Therefore, this option is incorrect.
- Inflammable: This word is used to describe something that is easily set on fire; readily combustible. This definition perfectly matches the phrase "liable to catch fire easily".
- Incombustible: This word describes something that cannot be burned; incapable of combustion. This is the opposite of what the question is asking for. Therefore, this option is incorrect.
- Extinguishable: This word describes something that can be put out, usually referring to a fire or light. While related to fire, it describes the ability to be stopped, not the ability to start easily. Therefore, this option is incorrect.

Additional Information on Inflammability and Flammability
It's important to note that the words "inflammable" and "flammable" mean the same thing: easily set on fire. The "in-" prefix in "inflammable" does not negate the meaning, as it does in words like "inaudible" or "incombustible". This can sometimes cause confusion, but both terms indicate a substance that is highly likely to catch fire. The term "flammable" is now often preferred in safety labeling to avoid this confusion, but "inflammable" is still correct and widely used, especially in older contexts or general vocabulary questions.
