Abashev

Abashev (; masculine) or Abasheva (; feminine) is a Russian last name. Variants of this last name include Abashenko (), Abashin/Abashina (/), Abashkin/Abashkina (/), Abashichev/Abashicheva (/), Abashkov/Abashkova (/), and Abashurov/Abashurova (/).
There are two theories regarding the origins of these last names. The first one relates them to nicknames "" ("Abash") and "" ("Abasha"), the diminutive forms of which are "" ("Abashka"), "" ("Abashko"), and "" ("Abashur"). Patronymic "" ("Abashich") is also derived from these nicknames. The nickname itself has either Russian or Turkic origins. In Russian, it could have been given to people who overused the dialectal Russian word "" ("abo"; meaning "or", "if only", "so that")—in this case the suffix "" ("-ash-") is a standard means of forming a name. The Turkic origin theory is more plausible and traces the nickname to the Turkic root "aba" (meaning "an uncle on the father's side"), to which diminutive suffix "-š" was added.
The other theory traces these last names, in particular Abashin and Abashkin, to the Christian male first name Avvakum.
