Questions & Answers about Альпинист лезет наверх, в то время как скалолаз отдыхает.
Why use лезет instead of лазает or лазит in this sentence?
лезет is the unidirectional verb of motion, meaning the climbing is happening in one specific direction right now. Because the mountaineer is currently making his way наверх (upwards), the action is a single, continuous, one-way movement. If we were talking about climbing as a general habit, we would use the multidirectional verb лазает (or лазит).
Why is it наверх instead of наверху?
наверх means 'upwards' and indicates direction (answering the question куда? - where to?). You use it with verbs of motion like лезет. наверху indicates a static location ('at the top', answering где? - where?), which would mean he is already resting at the top.
Can I just use пока instead of в то время как for 'while'?
The word скалолаз looks like a compound word. Is it related to the verbs of motion we are studying?
