🔹 Introduction

These prepositions show how movement happens — the path or direction someone/something follows.

👉 Simple idea:
They answer “How did it move?”

🔵 1. ACROSS = From one side to the other (surface/area)

👉 Use “across” when something moves from one side to the other side of an area

🧠 Easy Idea:

👉 ACROSS = side to side

✅ Examples:

• She walked across the road
• He swam across the river

🔴 2. THROUGH = Inside something (like a tunnel/room)

👉 Use “through” when movement is inside something

🧠 Easy Idea:

👉 THROUGH = inside movement

✅ Examples:

• The train went through the tunnel
• He walked through the forest

🟢 3. ALONG = In a line (road, river, path)

👉 Use “along” when movement is in a straight line

🧠 Easy Idea:

👉 ALONG = follow a line/path

✅ Examples:

• He walked along the road
• She ran along the river

🟡 4. UP = Movement to a higher place

👉 Use “up” when something moves higher

🧠 Easy Idea:

👉 UP = go higher

✅ Examples:

• He climbed up the hill
• She ran up the stairs

🟣 5. DOWN = Movement to a lower place

👉 Use “down” when something moves lower

🧠 Easy Idea:

👉 DOWN = go lower

✅ Examples:

• He ran down the hill
• She walked down the stairs

🎯 Quick Comparison

• across → side to side
• through → inside
• along → in a line
• up → higher
• down → lower

🧠 Golden Trick

👉 Across (surface) vs Through (inside)
👉 Up (↑) vs Down (↓)
