Respect

To see or to look again. To paraphrase the old carpentry adage: look twice, then act.
 
The verb ‘to respect’ has its origins in Proto-Indo-European (PIE) spek (to observe) and Latin specere (to look at). Add Latin re- (back to the original place, again, anew, once more) to specere and you get respicere (to look back at, regard, consider) and later respectere.
 
The noun respect (e.g., as a relationship of respect or regard) is from the late 14th century. The verb ‘to respect’ comes to English through medieval French respecter in the 1550s. The notion of respect as a feeling of esteem based upon the actions or attributes of someone or something or as the courteous or considerate treatment due to personal worth or power are from the 1580s. The term ‘self-respect’ is from 1795.  
 
PIE spek is also the root of words such as aspect, auspices, auspicious, circumspect, despicable, espy, expect, inspect, introspect, perspective, prospect, scope, skeptic, specimen, spectacle, spectrum, speculate, speculum, suspect, and many more.
