send out light, heat, gas, etc.
To send out light, heat, gas, a smell, or noise into the air or space around something.
用法パターン：
[something] emits [something]
よくある間違い：
Learners sometimes confuse "emit" with the more common phrasal verb "give off". "Emit" is more formal and is often used in scientific or news contexts, especially about gases, light, and radiation. There is also spelling confusion with "omit" (leave out), which has a completely different meaning.
類義語
give off (More informal and common in everyday speech, but usually not used in very technical writing.)
|
release (Focuses more on letting something go free; slightly broader and less tied to light/heat/sound.)
対義語
absorb (Describes taking in light, heat, or other energy instead of sending it out.)
|
contain (Emphasizes keeping gas, smell, or energy inside rather than letting it escape.)

produce a sound or remark
To make and send out a sound, word, or cry from your mouth or body.
用法パターン：
[someone or something] emits [a sound/word/cry]
よくある間違い：
Learners may try to use "emit" for normal speaking, like *"He emitted that he was tired"*, which is incorrect. For speaking, use "say" or "tell". Use "emit" only for sounds, cries, or very short spoken reactions in more formal or written styles.
類義語
utter (A formal word that focuses on speaking sounds or words, often used in similar contexts to this sense of "emit".)
|
let out (More informal; common in everyday speech for sounds like a sigh, scream, or cry.)
対義語
