While the government was forced to acknowledge the rising inflation rates, officials maintained that the underlying economy remained robust enough to withstand the pressure.
Recorded since 1553, a blend of Middle English aknowen (“to recognize, acknowledge”) and knowlechen (“to discover, reveal, acknowledge”). The former verb is from Old English oncnāwan, ācnāwan (“to know, recognize, acknowledge”), from on + cnāwan (“to know”). The latter is derived from the noun at hand in knowledge. For the formation compare Latin agnōscō and Russian призна́ть (priznátʹ), with cognate roots. The /k/-sound was preserved by being redistributed to the preceding syllable: /əˈkn-/ > /əkˈn-/. The -c- was inserted accordingly to reflect this pronunciation more clearly.
The verb is transitive and takes a direct object; often followed by a 'that' clause or a gerund.
