【Consider】 , 【regard】 , 【account】 , 【reckon】 , 【deem】 denote to hold the view or opinion that someone or something is in fact as described or designated. They are often used interchangeably, but there are shadings of meaning that allow them to be discriminated.

【Consider】 suggests a conclusion reached through reflection.

【Regard】 may retain its primary implication of looking upon. Sometimes it suggests a judgment based on appearances.

Often it implies a point of view, sometimes merely personal, sometimes partisanx.

【Account】 and 【reckon】 to some extent retain their basic implications of counting or calculating, and in comparison with the other terms they stress such value-related factors as evaluation and differentiation.

【Deem】 is somewhat literary. It is often used as the equivalent of 【consider】 , but it distinctively stresses judgment rather than reflection.
