Learn Hardcore Russian: Я схожу в магазин.

The square brackets signal that including the prefix с- is optional. In this case, writing схожу (with the prefix) versus хожу (without it) changes the nuance of the verb. The form схожу often implies a one-time, complete trip (going to the store and coming back), while хожу can express a habitual or ongoing action (regularly going to the store).

What is the difference in meaning between схожу and хожу?

Схожу comes from the perfective verb сходить, which is typically used to talk about a single, completed action—often a quick errand where you intend to return home. In contrast, хожу is derived from the imperfective verb ходить, meaning that it can refer to a habitual or repeated action. So, if you plan to make a one-off trip, схожу is appropriate; if you mean to say that you regularly go to the store, хожу fits better.

How should I decide whether to include the prefix с-?

Your choice depends on the context. If you want to express that you will make a single, round-trip journey (for example, "I will run to the store and come back"), use схожу. However, if you're describing a regular or habitual action ("I go to the store often"), then хожу without the prefix is the better choice.

Does the use of square brackets affect how the sentence is pronounced or its grammatical structure?
