Simple RAW for 5e V: The Disadvantage Strikes Back

[heavyfuel]

Q 45 - Clarification Request

A45: Your speed is how far you move during your turn. Instinctive Pounce allows you to move an additional amount (half of your current speed) during someone else's turn.

While there are a few abilities that allow you to move as a reaction, and I couldn't find consensus on the Internet, the book does say:

"Every character and monster has a speed, which is the distance in feet that the character or monster can walk in 1 round."

But also: "When you take the Dash action, you gain extra Movement for the current turn."

So, are Movement and Speed separate things?
