Semantic studying of meaning. Words have more than one meaning. Sentences have more than one meaning. When I say 'dog' or 'pumpkin' I have my own meaning, while you have yours. To really understand the meanings of language, we study semantics. The language doesn't have to be spoken, it can be something written or gestured through body language or kinesthetic signs and codes.
One somewhat extreme example is "woman". Literally, based on dictionary, woman means a female human. But the way someone may say it might indicate that "woman" is something lovable or disliked. Society's opinion on the word can influence its meaning. Meaning can also be influenced by social class.
For Example :
1. Grammatical Meaning: "Smells" means "Has smell"
2. Contextual Meanings:
Sister fell off the motorbike
I fell in love
His pride fell
