Etymology
From Late Middle English acute (“of a disease or fever: starting suddenly and lasting for a short time; of a humour: irritating, sharp”), from Latin acūta, from acūtus (“sharp, sharpened”), perfect passive participle of acuō (“to make pointed, sharpen, whet”), from acus (“needle, pin”). The word is cognate to ague (“acute, intermittent fever”). As regards the noun, which is derived from the verb, compare Middle English acūte (“severe but short-lived fever; of blood: corrosiveness, sharpness; musical note of high pitch”).

It was an acute event.
Surprisingly, this analysis revealed that acute exposure to solvent vapors at concentrations below those associated with long-term effects appears to increase the risk of a fatal automobile accident. Furthermore, this increase in risk is comparable to the risk of death from leukemia after long-term exposure to benzene, another solvent, which has the well-known property of causing this type of cancer.

The nimble Fly's Wings quicker were / Than those of her Competitor [a bee], / As may by this appear; / For an acuter Tone they made, / And in a ſharper Key they play'd, / (Which made the matter clear.)
1751, “a Lover of the Mathematicks” [pseudonym; Nathaniel Whittemore?], “Part II. New Paradoxes Solved.”, in A Mathematical Miscellany, in Four Parts., London: Printed for M. Cooper, […], →OCLC, paradox 61, stanza III, page 53:The acuteness of sound in stringed instruments depends on three circumstances—length, thickness, and tension. The shorter, smaller, and tighter a string, the more acute the sound. […] In the violin, when you desire an acute sound, you tighten the string. When you wish a loud sound, you draw the bow over the strings heavily.

2013, Thomas Keneally, Shame and the Captives, North Sydney, N.S.W.: Random House Australia, →ISBN; 1st Atria Books hardcover edition, New York, N.Y.: Atria, 2015, →ISBN, page 87:Miss Darcy was tall, and on a larger scale than Elizabeth; and, though little more than sixteen, her figure was formed, and her appearance womanly and graceful. She was less handsome than her brother; but there was sense and good humour in her face, and her manners were perfectly unassuming and gentle. Elizabeth, who had expected to find in her as acute and unembarrassed an observer as ever Mr. Darcy had been, was much relieved by discerning such different feelings.

Urgent.
[…] Ahab rapidly ordered the ship's course to be slightly altered, and the sail to be shortened. The acute policy dictating these movements was sufficiently vindicated at daybreak, by the sight of a long sleek on the sea directly and lengthwise ahead, smooth as oil, and resembling in the pleated watery wrinkles bordering it, the polished metallic-like marks of some swift tide-rip, at the mouth of a deep, rapid stream.

Chlorophosphuret of nitrogen (at ordinary temperatures) is a solid crystalline body. […] The form of the crystals, as obtained by sublimation, is that of a rhomboid, of which the obtuse angle measures 131° or 132°, the acute 48° or 49°: the acute angle of this rhomboid, either at one or both ends, is often truncated, when of course the angle formed is about 114°: the hexagonal prism is also found.

(of a triangle) Having all three interior angles measuring less than 90 degrees.
an acute triangle
In order to be an acute triangle, all three angles of a triangle must be less than 90°. These triangles can have very prickly personalities. So, if you want to create images of porcupines, rugged mountains, or narrow pine trees in your geometric design, you may best do it by using acute triangles[…]. The most commonly used acute triangle in quiltmaking is the equilateral triangle[…]. All three of its angles are 60°.

(historical) Of an accent or tone: generally higher than others.
Let this [the word alalal] be ſpoken as an Engliſh word, with the ſtrong accent on either ſyllable, or, on each, in repeating the word; and, no change of articulation diſturbing the ear, it will be abundantly evident that, with ordinary Engliſh pronunciation, the strengthened syllable has always the acuter tone, or, in muſical phraſe, the higher note.

Of particular relevance to the ICU [intensive care unit] setting is ketorolac, a NSAID [non-steroidal anti-inflammatory drug] that is being increasingly used for pain control in order to avoid problems of respiratory depression, sedation, and addiction associated with narcotics. […] ICU patients, who typically are under great stress from an acute illness that is often accompanied by multiorgan dysfunction including renal insufficiency, are especially prone to develop renal complications from ketorolac[…].

Of a short-lived condition, in contrast to a chronic condition; this sense also does not imply severity.
Bats host many high-profile viruses that can infect humans, including severe acute respiratory syndrome and Ebola. A recent study explored the ecological variables that may contribute to bats’ propensity to harbor such zoonotic diseases by comparing them with another order of common reservoir hosts: rodents.

2017, [Michael] Mitchell, [Susan] Wightman, “Foreign Languages”, in Typographic Style Handbook, London: MacLehose Press, →ISBN, section 10.2.1 (Commonly Used Accents), page 143:A more conservative approach, particularly if your author is a skilled computer user, would be to replace the problem characters with simple words or codes that are guaranteed to transfer successfully between computers. For example, you could replace é with e-acute if that particular character is causing problems. […] The author could then do a search and replace to change all instances of e-acute back to é before publication.
