F adjectives are especially useful when a general description does not say enough. Instead of calling something very weak, you might call it feeble. Someone who is extremely angry can be furious, while a plan that is practical enough to carry out can be feasible.
Everyday choices such as fast, fair, fresh, friendly, and funny cover plenty of common situations, while words such as facetious, formidable, forthright, and frivolous give you more precision. Start with the quick list, then use the examples and word comparisons to see how the adjectives differ in context.

Fictional or Fictitious?
Fictional and fictitious can overlap because both can describe something invented rather than real, but their typical uses differ.
Fictional is especially natural for characters, places, events, or worlds created as part of fiction.
Sherlock Holmes is a fictional detective.
Fictitious emphasizes that something has been invented and does not actually exist or is not true.
The suspect gave police a fictitious address.
You may see either word for invented characters, but fictional character is the more natural choice when discussing literature, films, or storytelling.
Farther or Further?
Farther and further have overlapped for centuries, so the common rule that farther is always physical and further is always figurative is too strict.
Both can refer to greater distance.
We walked farther along the trail.
We walked further along the trail.
As adjectives meaning more distant, both are also possible.
They could see lights on the farther shore.
However, further is the standard modern choice when you mean additional.
Further research is needed.
Please contact us if you need further information.
So the practical distinction is:
- for distance, farther and further can both work
- for additional, use further
Flammable or Inflammable?
These two words look as though they should be opposites, but they mean the same thing.
Both flammable and inflammable describe something that can catch fire easily.
Keep flammable materials away from the heater.
The in- in inflammable does not mean “not” in this word.
Because the spelling can cause confusion, flammable is usually the clearer choice when safety matters.
The opposite is nonflammable, not inflammable.
