Learn Turkish: Kurye ofise ulaşmak için hızlı koşuyordu. - The courier was running fast to reach the office.

We use the infinitive verb ulaşmak (to reach) followed by the word için (for). Together, ulaşmak için means 'in order to reach'. Whenever you want to say you are doing an action in order to do something else, you use this -mAk için pattern.

Why does ofis have the -e suffix in ofise?

The verb ulaşmak (to reach or arrive) always requires its target to be in the dative case (the direction suffix -e or -a). Even though we just say 'reach the office' in English, Turkish logic treats it as reaching to the office.

How is the verb koşuyordu built to mean 'was running'?

It uses the past continuous tense, which combines two time suffixes. We start with the verb root koş (run), add the present continuous suffix -uyor (running), and finally add the past tense suffix -du (was). Koş-uyor-du literally stacks up as 'run-ning-was'.

Does hızlı work as both an adjective and an adverb here?

Yes! While hızlı translates to 'fast' or 'quick', Turkish often uses adjectives directly as adverbs without changing them. You don't need a special suffix to turn it into 'quickly' before the verb koşuyordu.
