  • A mark (′ ) used to denote accentual stress, and also for other purposes. To denote stress in English, it is now generally placed after the accented syllable, as in this dictionary, but sometimes over the vowel of that syllable. The latter is done regularly in such Greek words as take this accent, and in all Spanish words the accentuation of which varies from the standard rule. In some languages it is used only to determine the quality or length of vowel-sounds, as on e in French (as in été), and on all the vowels in Hungarian; and in Polish and other Slavic languages it is also placed over some of the consonants to mark variations of their sounds. For other uses, see accent, n.
  • Keen may be the most objective of these words.

  • Shrewd differs from acute and keen by having an element of practical sagacity or astuteness. Only keen has the idea of eagerness: as, he was keen in pursuit. See astute and sharp.
  • To render acute in tone.
