1
very severe or intense (problem/pain)
Very strong or very serious, especially when talking about pain or a difficult problem.
Tipar de utilizare:
acute [problem/pain/need/shortage]
Greșeală frecventă:
Learners sometimes confuse 'acute' with 'cute' because they look similar. 'Cute' means 'pretty' or 'attractive in a small way'; 'acute' here means 'very serious' or 'very strong'. Also, learners may overuse 'acute' in everyday speech; in conversation, 'very bad' or 'really serious' is often more natural.
Sinonime
severe (The most common alternative in this sense; often used for strong pain or serious problems in both everyday and medical contexts.)
|
intense (Focuses on how strongly something is felt, especially emotions or physical sensations.)
Antonime
mild (Describes pain or problems that are not strong or serious, the opposite of 'acute' in this sense.)

2
sudden and severe but short (medical)
Used about an illness or medical problem that comes on suddenly and is very serious, but does not last a long time.
Tipar de utilizare:
acute [illness/infection/condition]
Greșeală frecventă:
Learners sometimes think 'acute' in medical contexts only means 'very bad'. It also contrasts with 'chronic': an acute illness is short-term and sudden, while a chronic illness is long-term, even if it is not very strong at every moment.
Sinonime
sudden (Emphasizes the quick start of the illness, but does not itself imply medical classification like 'acute' does.)
Antonime
chronic (The standard medical opposite; describes illnesses that last for a long time or keep coming back.)

Sinonime
keen (Very close in meaning; common in phrases like 'keen mind' or 'keen sense of smell'.)
|
sharp (Focuses on intelligence or quick understanding; slightly more informal in everyday speech.)
Antonime
