Notes on Different Meanings

• The two primary meanings of "lúp" belong to completely different fields (optics and botany/woodworking). The intended meaning is always clear from the context, such as the words it is paired with (e.g., "dùng" - to use, implies the optic tool; "gỗ" - wood, implies the timber).
