Words and terms are related concepts. A word is the smallest unit of language that community messages to the audience. It can be a chain of letters or sounds found between spaces or pauses. For something to be regarded as a word, it has to be meaningful, the audience must understand, and some people must agree on how it is used. Terms, on the other hand, are types of words: all terms are words or forms of words, but all words are not terms.
A term is a unique used word in a specialized field. For example, ‘sternum’ is a medical term for bone. A term can also be seen to have a different meaning in a situation than it does in normal use. For example, the word ‘particular’ usually means something that is unique, but in logic, the word ‘particular’ means a sentence that is true in some cases, but not in all.
In everyday use, the first ‘particular’ is a word while in logic, the latter ‘particular’ is a term. The term is more formal and is most associated with scientific or medical matters. ‘Word’ is neutral, except in slang, and it can be found in any type of media. Many misuse the word ‘term’ because they see it as a fancier word for ‘word.’ It is not. It has a different meaning.
