"Builds up on" is a phrasal verb that typically refers to the gradual accumulation or increase of something over time, particularly in the context of knowledge, experience, or physical substances.
In a literal sense, it can mean the gradual formation or layering of a substance on top of an existing surface. For example, when plaque builds up on teeth, it indicates the gradual accumulation of bacteria, food particles, and other substances that eventually form a hard substance.
Metaphorically, "builds up on" can describe the gradual acquisition or aggregation of knowledge, skills, or expertise. This suggests that as an individual or group gains more experience or accumulates more information over time, their knowledge or competency becomes more comprehensive or advanced. For instance, a scientist builds up on existing research when they conduct experiments or analyze data in order to expand the knowledge base in a particular field.
Additionally, "builds up on" can also imply the accumulation or build-up of emotions, tension, or stress. This could indicate a situation where negative feelings or pressure gradually intensify or worsen due to unresolved conflicts, repeated incidents, or prolonged exposure to certain circumstances.
Overall, "builds up on" suggests a gradual growth, increase, or accumulation of something, whether it be physical substances, knowledge, skills, or emotional aspects.
