Learn Turkish: Bu satıcı tilki gibi kurnaz. - This seller is cunning like a fox.

When using gibi (like/similar to) with regular nouns, the noun stays in its dictionary form without any case endings. You only need to add the genitive case ending (like -in or -im) when using gibi with most personal or demonstrative pronouns, like benim gibi (like me) or bunun gibi (like this).

Why does tilki gibi come before kurnaz?

In Turkish, modifiers (words or phrases that describe something) usually come directly before the word they describe. Here, the phrase tilki gibi (like a fox) describes how the seller is kurnaz (cunning), so it sits right in front of the adjective.

How do we get the word satıcı (seller)?

It comes from the verb satmak (to sell). The suffix -ıcı (or -ici, -ucu, -ücü depending on vowel harmony) is added to a verb root to describe a person or thing that does that action. It works a lot like the '-er' in the English word 'seller'.
