How to say "foam" in Japanese
Choosing the right word
- 泡あわnounThe everyday word for foam, froth, suds, or bubbles — beer foam, soap suds, bubbles in water. This is the word you want in almost all ordinary physical contexts.
- 水泡すいほうnounLiterally 'water foam'; covers foam and bubbles but is chiefly used figuratively, as in efforts or hopes turning to nothing (水泡に帰す). Seldom the word for literal foam.
Use 泡 for foam or bubbles in everyday contexts; 水泡 is a more literary word, also used figuratively for plans or efforts coming to nothing.
