Běžet: Já běžím. Ty běžíš. On/ona/ono běží. My běžíme. Vy běžíte. Oni/ony/ona (plurál) běží.
What is the difference between běhat and běžet. Both are imperfective, correct?
The difference is the same as in "chodit" vs "jít", eg. indeterminate (habitual) vs determinate.
Copying from T&N for Movement:
- Determinate verbs of motion are used for single, one-directional, goal-directed movements.
- Indeterminate verbs of motion are used for repeated, habitual, multi-directional, general (non-goal-directed) movements.
So, which Czech verb is determinate and which is indeterminate? In English I think of "is running" as an action going on right now, and "runs" as a general, habitual action.
determinate: jít, jet, běžet, letět
indeterminate: chodit, jezdit, běhat, létat
