Semiotics:a sign has two parts

http://users.aber.ac.uk/dgc/Documents/S4B/sem02.html

A sign consists of the  signified and the signifier

If what is signified is love,the signifier may vary … it can be a  “x “.a bunch of flowers,a poem.

Of course it may be misunderstood if two people come from different cultures/countries  or even different parts of the same country with maybe a different form of Christianity,with an atheisitic family etc

Some people tend to see a meaning in an act or word that was not intended…if carried too far it can lead to paranoia…I can imagine writing a funny play based on such confusion

Signifier

From Wikipedia, the free encyclopedia
 
 

Ferdinand de Saussure theorizes that a “sign[clarification needed] has two parts: signifier and signified. The signifier is the form that the sign will take, whether it be a sound or image and the signified is the meaning that is conveyed.

Example

Signifier: the word ‘tree’ = Signified: the mental image of a tree.

Charles Sanders Pierce analyzed sign systems and came up with the following: An Icon signifies by resemblance. An Indexical sign signifies by causal connection and finally, a Symbol signifies by learned convention.

Language can only deal meaningfully with a special, restricted segment of reality. The rest, and it is presumably the much larger part, is silence.”
