What is the part of writing called under headline?

The part of writing that comes directly under the headline is called the lead or lede.

Here's why it's important:

* Grabs attention: The lead is the first thing readers see, so it needs to be engaging and entice them to continue reading.

* Sets the tone: It establishes the style and overall feel of the piece.

* Provides context: It should give readers a clear idea of what the article is about and what they can expect to learn.

There are many types of leads, including:

* Summary lead: Provides a concise overview of the main points.

* Anecdotal lead: Starts with a personal story or experience.

* Question lead: Poses a question to draw the reader in.

* Quote lead: Starts with a compelling quote from a source.

The best type of lead depends on the topic, audience, and the overall goal of the writing.
