Fundamentals of Communication Theory and Linguistics

The Process of Communication

Communication consists of several key elements: the transmitter (who encodes and sends the message, taking the initiative), the code (a set of signs and rules), the receiver (who receives and decodes the message), the message, and the channel (spoken or written).

Functions of the Transmitter

• Emotional: Expressing feelings like pain or joy.
• Conative: Imperative or persuasive language.
• Phatic: Establishing or maintaining the communicative act (e.g., "Hello, can you hear me?").
• Aesthetic: Focusing on the form and beauty of the message.
• Referential: Communicating objective information or intention.
• Metalinguistic: Using language to describe language itself.

Communication Channels

• Visual codes: Written language, gestures, traffic signals.
• Acoustic codes: Speech, whistling.
• Tactile codes: Touch, Braille.
• Olfactory codes: Scents and animal pheromones.

Signs and Meaning

Signs are constructed through a relationship between the signifier (the perceptible form) and the signified (the concept evoked). This relationship is often arbitrary, which can lead to misunderstandings or "false friends."

Deixis and Pragmatics

Deixis refers to linguistic elements that point to circumstances, people, time, or space. It is studied within pragmatics, which analyzes the communicative situation.

• Personal: Signals the receiver (pronouns, possessives).
• Spatial: Indicates location (here, there).
• Temporal: Indicates time (now, tomorrow).

Discursive Context

The linguistic elements surrounding a text, both before and after, define the discursive context.

Nonverbal Communication

• Paralinguistic signs: Phonic (vocalizations, tone) and non-phonic (kinesics, looks, gestures).
• Proxemics: The study of human use of space and distance.

Semantic Relationships

• Synonymy: Different words with the same meaning.
• Polysemy: One word with multiple related meanings.
• Hyperonymy: A broad category containing specific sub-types (e.g., vehicle: car, bus).
• Homonymy: Same spelling/sound, different meaning.
• Homophony: Phonetic identity.
• Homography: Graphic identity.
• Paronymy: Similarity in form or sound.

Textual Properties

For a text to be effective, it must be:

• Adequate: Appropriate for the receiver, channel, and genre.
• Consistent: Well-organized, logical, and free of contradictions.
• Cohesive: Using repetition, ellipsis, synonyms, pronouns, and connectors to link ideas.

Linguistic Competence

Maintaining high standards requires avoiding errors in:

• Morphology: Gender, number, and verb forms.
• Syntax: Word order.
• Lexis: Word choice and foreignisms.
• Semantics: Misleading meanings.
• Prosody: Pronunciation.
• Orthography: Spelling.
