What does full mean?
Full is one of the most fundamental descriptive words in English, meaning filled to capacity or complete in extent. At its most literal, it describes containers, rooms, or vehicles holding as much as they can; at its most abstract, it signals totality — a full recovery, a full refund, the full story. It can also mark maximum effort or intensity, as in driving at full speed. Beyond physical and quantitative senses, "full" carries emotional resonance: a full life, a heart full of gratitude, or feeling full after a meal all suggest richness and sufficiency. Derived forms such as "fully", "fullness", and "fulfil" extend its reach through everyday language. Descended from ancient Germanic roots shared with Dutch and German words for completeness, it remains a short, sturdy word whose connotations of abundance and wholeness make it both practical and expressive.
Filled to capacity; containing as much as possible, or complete in extent or degree.
"The bus was so full that passengers had to wait for the next one."
Commonly used with "of": "full of energy", "full of mistakes".
The fullest amount, extent, or degree of something; also, in cricket, a ball bowled so the batsman can reach it easily (a full toss or full pitch).
"The team gave it their full until the final whistle."
To clean, shrink, and thicken cloth by beating and pressing it in water; a traditional step in textile-making.
"The mill once employed dozens of workers to full the woven wool."
In Old English, "full" doubled as an intensity booster — a poet might say someone was "full well" aware, meaning they were completely, absolutely aware.

Etymology of full
"Full" comes from the Old English "ful", deriving from a Proto-Germanic root (*fulnaz) shared with Old Norse "fullr", German "voll", and Dutch "vol". In Old and Middle English it served not only as an adjective but also as an intensifying adverb, appearing in expressions like "full well". Its derived relative "fulsome" originally simply meant abundant or plentiful before acquiring its modern negative connotation of excessive flattery.
