Questions & Answers about O adam çok inatçı ve mantıksız.
How is the word inatçı formed?
It comes from the noun inat, meaning "stubbornness" or "obstinacy". The suffix -cı (or -çı) is used to describe someone's profession or a strong habitual trait. Because inat ends in a hard consonant (t), the suffix must start with the hard consonant ç instead of the soft c to match. So, an inatçı is someone characterized by stubbornness.
What does the -sız suffix do in mantıksız?
The suffix -sız means "without" or "-less". It attaches to the noun mantık (logic) to create the adjective mantıksız (without logic, or illogical). This suffix is the standard way to turn a noun into a negative adjective in Turkish.
Why does inatçı end in -çı with an 'ı', when the last vowel in the root is 'a'?
The -cI / -çI suffix follows 4-way vowel harmony, meaning its vowel will be ı, i, u, or ü. The rule for 4-way harmony is that if the last vowel in the root word is a or ı, the suffix takes an ı. Since the last vowel in inat is a, the suffix correctly becomes -çı.
Can words ending in -cı and -sız be used as nouns too, or just adjectives?
They can be used as both! In this sentence, inatçı and mantıksız are describing o adam (that man), so they are functioning as adjectives. However, you can also drop the noun and use these derived words on their own to mean "a stubborn person" or "an illogical person."
