respectable

The word "respectable" is a relatively modern English formation, built upon the established noun "respect" which entered English in the late 14th century via Old French from Latin. The Latin source, respicere, literally meant "to look back at" (re- "back" + specere "to look"), a metaphor for giving consideration or regard. The suffix -able, of Latin origin via French, was productively attached to verbs and nouns to create adjectives indicating worthiness or capacity. Thus, "respectable" literally means "worthy of regard or esteem". Over time, its meaning evolved from the literal "deserving respect" to describe what society deems proper or correct, and further broadened to mean "fairly good" or "adequate", reflecting a social judgment of acceptability.

Structure: respect + able - respect: From Latin respectus ("regard, consideration"), from respicere ("to look back at, regard"). In this word, it functions as the core root conveying the concept of regard or esteem. - able: From Latin -abilis, a suffix forming adjectives meaning "capable of, worthy of, or tending to". In this word, it functions as an adjectival suffix meaning "worthy of".
