Learn Turkish: Ara sıra bu parka geliyoruz. - We come to this park now and then.

While you are learning how to ask "at what time" (saat kaçta) for specific events, ara sıra is a time frequency phrase meaning "now and then" or "occasionally". You use it to talk about how often you do something when there isn't an exact set time. Literally, it translates to something like "interval-row".

Why is there an "-a" at the end of "parka"?

The -a is the "to" or "towards" ending (known as the dative case). Because the verb gelmek (to come) involves movement toward a destination, you add -a (or -e, depending on the last vowel of the word) to that destination. So, parka means "to the park".

Why does the Turkish sentence use "geliyoruz" (we are coming) when the English translation says "we come"?

In Turkish, the present continuous tense (the -yor ending) isn't just for actions happening right this second. It is very commonly used for habits and routines, much like the English simple present tense. Because of the phrase ara sıra (now and then), we know this is a repeated habit, making "we come" the most natural English translation for geliyoruz here.

Could I include the word for "we" (biz) in this sentence?
