alt Hacker NewsAs a non-native speaker, English does have (what I think is) a rather unique phenomenon where the same verb can be used to express different shades of meaning (or sometimes wildly different meanings) depending on whether or which proposition is attached to it. "To step" means to take a step, but "to step up" means to confront something. When you "talk to" someone you converse with them, and when you "talk at" someone you monologue at them.

English uses a lot of prepositional phrase idioms. Now that I'm learning Japanese, I find there are relatively few like that (although not zero, compare "と相談" to discuss with and に相談" to consult). But it instead uses many, many compound verb expressions that are often not intiutive to a learner and just have to be memorized, so the effect is similar.
It also has words with opposite meanings like 断る (kotowaru, to reject, to ask permission), and 適当 (tekitou, suitable, appropriate, half-assed, careless).
This is a feature among the Germanic languages (of which English is one).
In German, these are called splittable verbs, and they can appear in two forms: "upstep" and "step up," depending on the sentence structure. That makes "upstep" / "step up" seem more like a separate verb from "step," rather than just being the same verb with an adverb added on.
These are called phrasal verbs. https://en.wikipedia.org/wiki/English_phrasal_verbs
