Learn Turkish: Şu yüksek çalıya doğru dikkatli yürü. - Walk carefully towards that tall bush.

The word doğru works as a postposition meaning "towards" in this sentence. To say "towards something," Turkish requires that "something" to take the dative case (the "to/for" direction ending). So, we take çalı, add the buffer -y-, and the dative suffix -a to make çalıya doğru.

Why use şu for "that" instead of o?

While o is the standard word for "that" (often for things further away or out of sight), şu is used specifically when you are pointing something out or drawing the listener's immediate attention to it. Since the speaker is directing someone's movement toward a specific bush right now, şu is the most natural choice.

Why is yüksek used for "tall" here instead of uzun?

While uzun translates to "tall" for people or "long" for objects, yüksek literally means "high." In Turkish, things that rise up from the ground like mountains, walls, buildings, and large bushes are often described as "high" (yüksek) rather than "long" (uzun).

Does dikkatli mean "careful" or "carefully" here?

It means "carefully" here. In Turkish, many adjectives like dikkatli (careful) can be used directly as adverbs to describe how an action is performed without adding any extra suffixes. By placing it right before the verb yürü, it naturally translates to "walk carefully."
