What does consummate mean?
Consummate functions as both a verb and an adjective, unified by the idea of reaching a highest or final point. As a verb it means to complete or bring to fruition, most famously in the phrase 'to consummate a marriage,' which traditionally refers to the act that legally confirms the union; it also applies to concluding deals, treaties, and business transactions. As an adjective it describes supreme skill or perfection — a consummate artist, liar, or professional is one whose command of their craft seems total. The word carries a formal, elevated tone: it lends gravity to legal documents and polish to critical praise alike. Derived from Latin roots meaning 'to bring to a summit or completion,' it has retained that sense of culmination for centuries, making it a precise and expressive choice whenever ordinary words like finish or skilled feel inadequate.
To bring to completion or fulfilment; to make final or complete, especially said of a marriage or an agreement.
"They consummated their marriage on the wedding night."
In legal contexts, consummation of a marriage historically affected the validity of the union.
Supremely accomplished or skilled; representing the highest degree of mastery or perfection.
"He handled the crisis with consummate ease."
The same word can describe both the legal completion of a marriage and a musician's flawless technique — because at heart it simply means 'brought to its highest point.'

Etymology of consummate
Consummate comes from Latin 'consummare' (or 'consummare'), meaning to sum up or complete, formed from 'com-' (together) plus 'summare', derived from 'summus' (highest). It entered English in the early 16th century, first as an adjective before developing verbal use. The same Latin root 'summus' gave English other words of height and taking-up, including summit, assume, consume, and presume.
