Sense: verb/1
'Overflow' is the best general verb when liquid goes past an edge because there is too much of it. 'Spill' often suggests an accident caused by movement, such as dropping a cup. 'Spill over' is very close to 'overflow' and is common when the extra liquid or people spread into another place. 'Flood' is stronger and usually means covering a larger area with water. 'Brim over' is more vivid and slightly more literary, often for something filled right to the top. So milk can 'overflow' from a pot, coffee can 'spill' when you bump the table, and a river can 'flood' nearby fields after heavy rain.
Common collocations
Etymology
Formed in English from 'over' and 'flow'. The basic idea was water going beyond an edge or boundary. From that literal picture, English later extended the word to full rooms, extra crowds, and even feelings that show themselves very strongly.
