Sense: adjective/1
Upper, higher, top, above, and overhead all relate to positions that are not low, but they are used differently. Upper is a positional adjective placed directly before a noun and contrasts with 'lower' — it points to the higher of two parts within a single object or area, such as 'the upper floor' of a building. Higher is a true comparative adjective that can be followed by 'than' ('higher than the roof') and works with measurable distances. Top refers to the absolute highest point or surface ('the top shelf') and implies nothing sits above it. Above is a preposition or adverb that describes a general position without touching ('a plane flying above the clouds'), while overhead specifically means directly above your head ('a ceiling fan spinning overhead'). For example, you might rest your arms on the upper edge of a fence (not the very top), but you would put a vase on the top shelf (the highest one).

Etymology
Upper traces back to Old English 'upp' (meaning 'up') combined with the comparative suffix '-ra.' It has been used since the 1300s to describe the higher or topmost of two things. The noun sense for the top part of a shoe appeared in the 1700s, and the slang term for a stimulant drug emerged in American English in the mid-1900s.
