Pro Tip
Positioning with nouns
Place 'all' before singular nouns (e.g., 'all the book') and after determiners like 'the', 'my', or 'this' when referring to a specific group.
Gold Rule
Avoid redundancy
Do not use 'all' with 'every' or 'each' in the same phrase (e.g., 'all every student' is incorrect).
Word Origin
Old English 'eall', of Germanic origin; related to Old High German 'al', Old Norse 'allr', and Latin 'omnis'.
Usage Notes
Used before singular nouns to mean 'every kind of' (e.g., 'all the time'). When used with plural nouns, it emphasizes the entire group. Avoid redundancy like 'all of them all'—use 'all of them' or 'them all'.
