Sense: adjective/1

All four words describe objects that are easy to carry or move, but they focus on different features. Light is the most general word and simply means 'not heavy' — a cardboard box can be light even if it is large. Lightweight compares the object to others of the same type: a lightweight laptop is lighter than most laptops, not just light in general. Compact emphasizes small size and efficient use of space rather than weight — a compact camera fits in a pocket but may not be especially light. Portable means 'designed to be carried easily' and focuses on convenience of transport, as in a portable speaker that runs on batteries. When buying hiking gear, you want something lightweight (light for its type) and compact (small when packed). For luggage, a lightweight suitcase means it weighs little when empty, so you can pack more without exceeding airline limits.

Etymology

Old EnglishEnglish

Lightweight is a compound word formed from Old English 'lēoht' (not heavy) and 'gewiht' (weight, heaviness). The physical sense has been in use since the 1500s. The boxing weight class was established in the early 1800s, and by the 1900s the word had taken on its figurative meanings — first for a person of little importance, and later for someone with low alcohol tolerance.
