1
send out light, heat, gas, etc.
To send out light, heat, gas, a smell, or noise into the air or space around something.
الگوی کاربرد:
[something] emits [something]
اشتباه رایج:
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.
هممعنیها
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.)
متضادها
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.
الگوی کاربرد:
[someone or something] emits [a sound/word/cry]
اشتباه رایج:
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.
هممعنیها
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.)
متضادها
silence (As a verb, it means to stop sounds or speech from being made, the opposite of producing them.)

To officially create and send out new shares, bonds, or money so that people can buy or use them.
الگوی کاربرد:

متضادها
withdraw (In finance, refers to taking money, notes, or securities out of circulation, the opposite of putting them into circulation.)
