What does fantastic mean?
Fantastic is an adjective with two main strands of meaning. In contemporary usage it almost always means extremely good, excellent, or impressive — a word of warm enthusiasm applied to everything from meals and performances to news and opportunities. Its older sense, still found in literary writing, describes things that are fanciful, bizarre, or imagined rather than real, a meaning preserved in words like 'fantastical'. The word comes ultimately from the Greek 'phantastikos', meaning capable of appearing to the imagination, via Latin and French, which explains why it once carried the idea of illusion or unreality before shifting toward praise. Today fantastic is informal to neutral in tone, pairs naturally with intensifiers like 'absolutely', and ranks among the most common ways English speakers express delight or admiration. Its blend of everyday usefulness and vivid history makes it both practical and etymologically intriguing.
Extremely good or impressive; excellent.
"We had a fantastic time at the festival."
The dominant modern sense; informal to neutral in register.
Fanciful, bizarre, or grotesque in appearance or conception; seemingly imaginary.
"The cathedral's gargoyles were carved into fantastic shapes."
An older, chiefly literary sense, now more often expressed by 'fantastical'.
Fantastic originally meant 'existing only in the imagination' — so calling your dinner 'fantastic' is literally saying it was too good to be real.

Etymology of fantastic
Fantastic derives from the Greek 'phantastikos', meaning 'able to create mental images', formed on 'phantazein', 'to make visible or appear'. It passed into medieval Latin as 'phantasticus' and reached English in the mid-16th century via French 'fantastique', first describing something imagined, illusory, or whimsically strange. Over the following centuries the word gradually shifted from suggesting unreality to expressing enthusiastic approval, and by the 20th century its dominant modern sense — 'excellent' — was firmly established. It shares its root with 'fantasy' and 'fancy', both of which descend from the same Greek family through Latin and French.
