Learn German: Eine humorlose Figur hat keine guten Eigenschaften. - A humorless character has no good traits.

It combines the noun der Humor (humor) with the suffix -los (meaning "without" or "-less"), creating the base adjective humorlos. It then gets the ending -e because it describes a feminine noun (Figur) in the nominative case after the indefinite article eine.

Why does humorlose end in -e but guten end in -en?

Eine humorlose Figur is singular, feminine, and in the nominative case, so the adjective takes an -e ending. In contrast, keine guten Eigenschaften is plural and in the accusative case. Adjectives that come after a plural negative article like keine always take the -en ending.

What does the suffix -schaft in Eigenschaften tell us?

The suffix -schaft turns a base word (here, the adjective eigen, meaning "own") into a noun representing a quality or state, similar to "-ship" or "-ness" in English. Nouns ending in -schaft are always feminine and form their plural by adding -en.

Why do we use keine to negate this sentence instead of nicht?
