With verbs such as ходить, плавать, ехать, летать, the fact that they are indeterminate means that they imply movement in many directions without a particular finish line.
However, the verb "to climb" itself has both an indeterminate version (лазить) and a determinate one (лезть).
But, since the act of climbing always happens upward, how come there can be an indeterminate climbing?
I guess there are differences in verb usage. Does лазить imply climbing up many things (
лазить по деревьям, for example) while лезть focuses on climbing a particular thing (
лезть на дерево)?
