常見錯誤
What are common mistakes with "Combustible"?Which "Combustible" sentences look correct but are wrong?
×The room was full of combustibles.
✓The room was full of combustible materials.
While 'combustible' can be used as a noun (combustibles), it is primarily an adjective. Learners often use it as a noun when the context calls for a noun phrase like 'combustible materials/substances' for clarity.
×This liquid is non-combustible, so it's safe. (Intending to mean it catches fire easily)
✓This liquid is highly combustible / flammable, so it's dangerous.
Learners may confuse 'combustible' with 'incombustible' or 'non-combustible'. 'Combustible' means 'able to catch fire and burn'. 'Incombustible' or 'non-combustible' means the opposite. Also note that 'inflammable' means the same as 'flammable' (easily set on fire), not the opposite.
×He has a combustible personality.
✓He has a volatile / fiery / explosive personality.
'Combustible' literally describes materials that can catch fire. When used metaphorically for people or situations (meaning easily angered or explosive), it is less common and can sound unnatural or overly literal. Words like 'volatile', 'fiery', or 'explosive' are more idiomatic for describing temperament.
×It is combustible material.
✓It is a combustible material. / It is combustible material.
When 'material' is used as a countable noun referring to a type or instance, the indefinite article 'a' is needed ('a combustible material'). The article can be omitted if 'material' is used in a more general, uncountable sense, but 'a' is very common in this context.
×combustable
✓combustible
A common spelling error is omitting the 'i' after the 't'. The correct spelling is 'combustible', following the pattern of other adjectives like 'convertible', 'perceptible'.
