Questions & Answers about Мы решили разделиться на подгруппы.
Why do we use the preposition на + accusative case for 'into subgroups'?
With verbs of dividing, splitting, or cutting (like разделиться), Russian uses the preposition на followed by the accusative case to show the resulting parts. It functions just like 'into' does in this specific English context.
Why is the reflexive verb разделиться used here instead of just разделить?
The non-reflexive разделить is transitive, meaning 'to divide something else' (like dividing a pizza or a budget). By adding the reflexive suffix -ся, the action reflects back on the subject. Therefore, разделиться means 'to divide ourselves' or 'to split up'.
How does the prefix под- change the meaning of группы in this sentence?
While под- often means 'under' in a physical sense, here it functions exactly like the English prefix 'sub-'. It turns группа (group) into подгруппа (subgroup), indicating a smaller, subordinate division within a larger whole.
Could we use the imperfective verb решали instead of the perfective решили here?
You would only use решали if you wanted to emphasize the process of deciding (meaning 'we were deciding' or 'we were trying to decide'). Because the focus here is on the single, completed result of the decision, the perfective решили is required.
