We communicate through symbols which are generally commonly-agreed-upon abstract representations of real-world objects and phenomena. The correspondence is usually clear but there’s a significant degree of fuzziness involved owing to unavoidable subjectivity inherent in even the most standardised definitions as well as differential human perception and understanding of objects and phenomena. Language in its narrow sense is the most commonly used means of communication, and in its broadest sense is the very term used to refer to any and all means of communication. No word, phrase, or sentence is a perfect point – its meaning dissipates around it in a fuzzy cloud and the nuclei of these clouds are slightly or even considerably different for different individuals in different contexts of place and time.
