Learn Turkish: İndirimdeki reyonda alan alana. - At the sale aisle, people are buying left and right.

This uses the chaotic abundance pattern from this lesson! It repeats the subject relative participle -an. First, alan means "the one who buys". The second word adds the dative suffix -a to make alana ("to the one who buys"). Together, the idiom alan alana literally means "buyer to buyer", expressing that everyone is buying in a frenzy.

Is this sentence missing a verb?

Yes, it is a nominal (verbless) sentence. In spoken and informal Turkish, this specific chaotic abundance pattern is often used entirely on its own. You do not need to add a verb like oluyor or a "to be" suffix like -dır at the end.

Why do we see the locative suffix twice here, in indirimdeki and reyonda?

They do two different jobs. The -de in indirimdeki pairs with the suffix -ki to turn the noun indirim (sale) into an adjective meaning "which is on sale". That adjective modifies reyon (aisle). The second locative, the -da in reyonda, gives us the location for the whole sentence: "at the aisle".

Can I build this chaotic pattern with any verb?
