Pro Tip
Avoid redundancy
Do not use 'completely full' or 'totally full'—'full' alone is sufficient to convey completeness.
Gold Rule
Adjective vs. Verb
Use 'full' as an adjective to describe a state (e.g., 'a full tank') and 'fill' as a verb to describe the action (e.g., 'fill the tank').
Word Origin
Old English 'full' (adjective), from Proto-Germanic '*fullaz', related to Old Norse 'fullr', Old High German 'ful', and Latin 'plenus'. The verb sense derives from the noun/adjective.
Usage Notes
As an adjective, 'full' is often used before a noun (e.g., 'full glass'). The verb 'fill' is commonly used to describe the action of making something full. Avoid redundancy like 'completely full'—'full' already implies completeness.
