"I wash" is typically more of a reflexive verb because it has the same semantic agent and patient (typically represented syntactically by the subject and the direct object).
in spanish :
"Lavo" es típicamente un verbo más reflexivo porque tiene el mismo agente semántico y paciente (típicamente representado sintácticamente por el sujeto y el objeto directo)
