1. Clever; sharp; shrewd; pretty or attractive.
2. Etymology: cute was originally a shortened form of acute in the sense of being "keenly perceptive or discerning, shrewd".

It is considered likely that cute came to be used as a term of praise, or approval, for things that demonstrated "acuteness", and so it went on to develop its own sense of being "attractive" and "fetching".

The increased sharpness of sense perceptions.

1. Abnormally acute (sharp and loud) hearing, sometimes resulting in pain even when only moderately loud sounds are in the area of the subject; formerly, hyperacousia.

1. An acute febrile state with chills.
2. A severe form of malarial paroxysm (in medicine, a violent attack which may be due to the sudden occurrence of symptoms or the acute exacerbation [the abrupt worsening] of preexisting symptoms).

Less than acute or referring to a disease or other abnormal condition which is present in a person who appears to be clinically well.

The ailment may be identified or discovered with a laboratory test or radiologic examination.

The term subacute is used in contrast to acute, which indicates "a very sudden onset or a rapid change"; and chronic, that indicates "an indefinite period of time or no change".

In ancient Greece, the "father of medicine", Hippocrates, distinguished diseases that were acute (abrupt, sharp and brief) from those that were chronic (illness or pain which is serious and that lasts for a long time) and his diagnosis is still being applied in these modern times.

Subacute has been coined to designate the mid-ground between acute and chronic.

Extremely acute; that is, describing pain which is very strong and sharp and marked by an extreme severity of symptoms and fast progress; such as, a disease.
