Answer: jargon
Explanation: Jargon refers to specialized or technical language that is used within a particular profession or industry. It is often used to convey complex ideas or concepts in a concise or efficient manner, but it can be difficult for people outside of the profession or industry to understand. "Drip campaign" and "gated content" are examples of jargon that might be used in the field of marketing.
Half truths, biased language, and generalizations are not the same as jargon. Half truths are statements that are only partially true or that are intended to mislead or deceive. Biased language refers to language that is used in a way that reflects a particular bias or perspective, rather than being neutral or objective. Generalizations are statements that are made about a group or category of things based on limited information or experience, and they may not be accurate or representative of all members of the group.
