Plain English Meaning
The three accepted ways to fly into a holding pattern. Which one you use depends on the direction you are coming from when you reach the holding fix.
Full Definition

The correct method is determined by the aircraft's heading relative to the holding course as it crosses the fix, using the published 70°/110° sector boundaries on the holding side.
Context Anchor
