“Fantastic” describes something that is extremely good, impressive, or imaginatively creative. First of all, people use it to express strong approval or excitement, especially when something turns out much better than expected.

In addition, the word can apply to things that are fictional or dream-like, such as a fantastic story filled with magical creatures.

Etymology:
The word “fantastic” comes from Latin phantasticus, meaning imaginary or unreal. First of all, this Latin term was shaped by Greek phantastikos, which relates to the power of imagination and creating mental images.
Moreover, in earlier usage, the root was linked to things that existed more in the mind than in reality. Later, during the Middle English period (via Old French fantastique), the word entered English with meanings tied to imagination and wonder. Over time, the sense expanded: in everyday modern English, it commonly signals excitement and praise, not just “made-up” or “unreal.” In addition, it can still describe something extraordinary in a way that feels beyond ordinary experience.
Therefore, today, “fantastic” can mean wonderfully creative or simply very good—depending on context and tone.
