first-degree + noun (burn)

文法句型

first-degree + noun (crime type)

用法筆記

Contrast with adj/1 and adj/2 — in medicine 'first-degree' means LEAST serious, but in law it means MOST serious. This opposite usage frequently confuses learners. The legal sense is predominantly used in American English; British English prefers 'murder' without the degree classification.

常見錯誤

He committed first-degree theft.
He committed first-degree murder / first-degree arson.
💡First-degree is only used for the most serious crimes like murder, arson, or assault where degrees exist, not for minor offences like theft.
A first-degree burn is like a first-degree murder — both are serious.
A first-degree burn is the mildest type of burn, but first-degree murder is the most serious crime.
💡The two uses have opposite meanings depending on the domain.
