I still remember these two words as a teacher. Let me show my shame and tell you~~ I have made a table for you. Let’s take a rough look at it first! ! !

1. Let’s first look at the difference in specific meanings of the two words

(1) The meaning of sign?

Sign can also be used as a noun and a verb. The noun means "sign; symbol; mark; gesture"; the verb means "signature; signing".

It has the broadest meaning. It can refer to a symbol or device, or it can also represent a visual display of emotion or personality, or it can also refer to a specific sign used for identification or instruction, such as a sign, a traffic sign, etc.

(2) The meaning of signal

Speaking of the word signal, I think of the popular Korean drama signal in 2016. The drama mainly tells the story of current criminal policemen and past criminal policemen. They talked through an old-fashioned walkie-talkie and solved a case that had not been closed for a long time.

You can understand the meaning of signal from the name of this Korean drama.

Signal can be used as a noun, verb and adjective. As a noun, it means "signal; code"; as a verb, it can mean "to send a signal to...; to notify by signal", such as danger signal, distress signal, radio signal, etc.
