What is the latin word for novel?

The Latin word for 'graphic novel' could be 'liber graphicus' (though this is a bit of a constructed term as there may not be a single, traditional Latin term precisely for 'graphic novel').

The Latin word for 'fiction' is 'fictio'.

No. The graphic novel is a modern concept and Latin, being an ancient language, doesn't have a term specifically for it.

The latin word for life story is 'vita fabula'.

The Latin word for 'little story' is 'fabella'.

Well, to be honest, I'm not sure exactly what the equivalent of 'fiction' is in Latin. But usually, words like this have roots that suggest imagination or creation.

The word whale is derived from the word whale in latin.

Well, in ancient Rome, the word 'novus' (the Latin word related to 'novel') was used quite broadly. In the realm of literature, when poets or storytellers were creating something that deviated from the norm, they could use 'novus' to convey that sense of newness. For instance, if a playwright was writing a play with a new type of plot structure or character development, 'novus' could be used to describe it. Outside of literature, in the political and social arena, 'novus' was used to talk about new policies, new leaders who brought new ideas, or new social classes emerging. It was a fundamental word in the Latin vocabulary for expressing the concept of newness, which is related to the modern concept of a 'novel' as a new form of literary work.

The Latin word 'fictio' can be used to trace the etymology of the English word 'fiction' in modern language study.

The Latin word for life story, say 'vita fabula', is not really used as it is in modern English. But its influence is there. English has borrowed a lot from Latin. For instance, the idea of a narrative about someone's life, which is what 'vita fabula' represents, is expressed through words like 'biography'. Also, Latin roots give us words like 'vital' which is related to 'vita' and implies something crucial to life. And when we look at words like 'fable' related to 'fabula', we can see how the concept of story - telling has evolved from Latin. It's all about how Latin has seeped into the English language over time.
