Vanessa compares the phrasal verbs “work on” and “work at.” They can both describe effort, but they do not always fit the same object. The lesson’s central distinction is useful for learners who want to talk about projects, skills, or personal qualities precisely. Pay attention to the noun or activity after the phrase, and learn the examples as complete chunks rather than translating each preposition separately.
“Work on” commonly means spend time and effort improving, developing, or completing a task, project, or skill. Someone can work on a presentation, work on pronunciation, or work on a plan. “Work at” often emphasizes sustained effort applied to an ability, habit, or quality. Vanessa models “working at improving my exercise skills,” where the focus is the effort of developing a capability. The boundary is not an absolute grammar formula; usage depends on the specific expression and context.
Both phrases can take an -ing form after “on” or “at,” as in “work on improving” or “work at improving.” The preposition is part of the phrase, so learners should notice which combinations sound natural in the example. If uncertain, check a reliable dictionary or corpus and learn the entire pattern. A phrase such as “work on the report” points to a particular task, while “work at being more patient” focuses on making an ongoing personal effort.
When explaining your own goals, the distinction can make the sentence more specific. You might say, “I’m working on my pronunciation” when naming a skill or area of improvement. You could say, “I’m working at being more patient” when emphasizing continued effort toward a quality. A listener will usually understand either way from context, but noticing the common patterns helps speech sound more natural.
To practise, name one concrete project and one ongoing personal goal. Write or say a sentence with “work on” for the project and “work at” for the effort. Then compare the meaning: what is the object of your effort, and does the sentence emphasize a task or a continuing practice? The goal is not to memorize a rigid rule, but to recognize typical collocations and use them consistently in context.
