  'aakar' is the full form without tense suffix. Vowel harmony with tense see 'aakur-u' and 'aakir-i'; possibility of total vowel reduction 'aakr-i/u'; change of stem with subordinator, see 'aakit-ka/kama/su.
  As an aspect, 'aakar' can take the valor of resultative and progressive. For this one, it is in variant with 'baakar'. It enters also in the compounded aspect 'kamaakar' (kama+aakar) that has the valor of prospective (to be ready to).
