"Keep" means to maintain or hold, while "keep on" implies continuing an action without stopping.

Key Differences

"Keep" generally refers to holding onto or maintaining something, like keeping a promise. In contrast, "keep on" suggests a continuous action, such as keep on walking, implying ongoing movement or activity.
In usage, "keep" can denote possession or maintenance of a state, like keeping something safe. "Keep on," however, often appears in more dynamic contexts, signifying the persistence of an action, like keep on trying.
The word "keep" can be versatile, used in various contexts from physical holding to emotional states. "Keep on," on the other hand, is more specific to actions and often used in motivational or persistent scenarios.
"Keep" can function independently as a verb, but "keep on" typically requires an object or action to follow, emphasizing the action's continuation.
In a grammatical sense, "keep" is a standalone verb, whereas "keep on" is a phrasal verb, adding the preposition "on" to denote ongoing action.
