Signal Meaning in English
word
释义
A signal is a sign, movement, sound, or message that gives information or tells someone to do something. It can also mean the electronic connection used by phones, radios, or networks.
用法与细微差别
Common in everyday and technical English. Frequent collocations include 'traffic signal', 'signal strength', 'clear signal', 'send a signal', and 'a signal that...'. Do not confuse it with 'sign': a 'sign' is usually a visible notice or symbol, while a 'signal' actively communicates information or instruction.
