Prompt Engineering Glossary

A comprehensive glossary of 30+ terms used in Prompt Engineering.


A​

AI (Artificial Intelligence) - Computer systems designed to perform tasks that typically require human intelligence, such as understanding language, recognizing patterns, and making decisions.

AI Assistant - An AI-powered tool designed to help users with tasks through conversation, like ChatGPT, Claude, or Google Gemini.

Audience - The intended readers or users of the content you're creating. Specifying audience helps AI adjust complexity and tone.


B​

Brainstorming - Using AI to generate multiple ideas, options, or creative possibilities for a topic or problem.


C​

Chain-of-Thought (CoT) - A prompting technique where you ask AI to show its reasoning step-by-step, often improving accuracy for complex problems.

Clarity - Being unambiguous and precise in your prompt so AI doesn't need to guess what you mean.

Claude - An AI assistant developed by Anthropic, known for its helpfulness and focus on safety.

Completion - The response or output that AI generates based on your prompt.

Context - Background information provided in a prompt that helps AI understand your specific situation, needs, and constraints.

Context Window - The maximum amount of text (including your prompt and AI's response) that an AI model can process at once. Larger context windows allow for longer conversations and documents.


D​

Default Behavior - What AI does when you don't specify something. Understanding defaults helps you know when you need to be explicit.


E​

Editing Prompt - A prompt asking AI to modify existing content—shorten, change tone, fix errors, or improve clarity.

Example (in prompting) - A sample you provide in your prompt to show AI what kind of output you want. See also: Few-Shot Learning.


F​

Few-Shot Learning - Providing one or more examples in your prompt so AI can learn the pattern, format, or style you want.

Format - The structure of the output you want—list, table, paragraphs, email, etc. Specifying format gives AI clear structural guidance.


G​

Generative AI - AI systems that create new content (text, images, audio, code) rather than just analyzing existing data.

GPT (Generative Pre-trained Transformer) - The architecture behind ChatGPT and similar AI models. Often used informally to refer to AI chatbots.


H​

Hallucination - When AI generates false, fabricated, or incorrect information that sounds plausible. Always verify important facts.


I​

Input - Your prompt—the text you send to AI. See also: Prompt.

Input-Output Pattern - A prompting technique where you show AI transformation examples (input → output) so it learns to apply the same transformation to new inputs.

Iteration - The process of refining your prompt based on AI's response to get closer to what you actually want. A key skill in prompt engineering.


L​

LLM (Large Language Model) - AI models trained on massive amounts of text that can understand and generate human-like text. Examples: GPT-4, Claude, LLaMA.

Length Specification - Defining how long you want the output—in words, sentences, paragraphs, or approximate size.


M​

Model - The specific AI system you're interacting with (GPT-4, Claude 3, etc.). Different models have different capabilities and limitations.


N​

Natural Language - Ordinary human language (as opposed to programming code). AI assistants are designed to understand and respond in natural language.


O​

One-Shot Learning - Providing a single example in your prompt to show AI the pattern you want. See also: Few-Shot Learning.

Output - What AI generates in response to your prompt. See also: Response, Completion.

Overloading - Including too many requirements in a single prompt, which can confuse AI and produce poor results.


P​

Persona - A role or character you ask AI to adopt (e.g., "You are an experienced marketing consultant"). Can influence tone and approach.

Prompt - The text input you give to an AI system—your instruction, question, or request that guides what the AI generates.

Prompt Engineering - The skill of crafting effective prompts to get better results from AI systems.

Purpose - Why you need the content and what you want to achieve with it. Clarifying purpose helps AI create more useful output.


R​

Refinement - Adjusting your prompt or asking for modifications to improve AI's output. Part of the iteration process.

Response - What AI generates based on your prompt. The quality of the response depends heavily on the quality of your prompt.

Role Prompting - Starting a prompt by defining AI's role ("You are a financial advisor...") to influence the perspective and expertise in the response.


S​

Specificity - The level of detail in your prompt. More specific prompts generally produce more relevant and useful results.

System Prompt - Hidden instructions that set the AI's behavior and context. In ChatGPT's custom instructions or when using APIs.


T​

Temperature - A setting that controls randomness in AI outputs. Higher temperature = more creative/varied; lower = more focused/deterministic.

Token - The basic unit of text that AI processes. Roughly corresponds to word parts. Important for understanding context window limits.

Tone - The feeling or voice of the content—professional, casual, friendly, serious, etc. Specifying tone helps AI match your communication style.

Transformation Prompt - A prompt asking AI to change content from one form to another—like summarizing, translating, or reformatting.


V​

Vague Prompt - A prompt lacking sufficient detail, forcing AI to make assumptions that may not match your intent.

Verification - Checking AI's output for accuracy, especially for facts, data, or important information. Essential because AI can hallucinate.


Z​

Zero-Shot - Asking AI to perform a task without providing any examples. The AI relies entirely on its training and your instructions.
