Introduction

What’s the difference between I worked hard last night and I hardly worked last night?
Or between I still haven’t done it and I haven’t done it yet?
There are many confusing words in English that students often use incorrectly.
Today, you’ll learn how to use 21 confusing but very common English words correctly.

Hard vs. Hardly

Hard means “with effort or intensity.”
Example: I worked hard this weekend = I worked a lot.

Hardly means “almost not” or “barely.”
Example: I hardly worked this weekend = I worked very little.

You cannot say he works hardly every day. Instead, say he works hard every day.

You can also use hardly in sentences like I hardly slept last night (I slept very little).
There’s no equivalent like slept hard—instead, say I slept well or I slept like a rock.

Late vs. Lately

Late = after the scheduled or usual time.
Example: We arrived late because we stayed up late last night.

Lately = in recent days or weeks.
Example: Lately, I’ve been watching a lot of your videos.

You can even have late and lately together: Lately you’ve been showing up late.
