Hard or Hardly? 8 Words That Flip Meaning When You Add -ly

The rule you learned has a small exit door

Add -ly to an adjective and you get the adverb. Quick becomes quickly, careful becomes carefully, and the meaning comes along unchanged. That works for almost every word in English. For a handful of extremely common ones it does not, and those are the ones you use most. He works hard and he hardly works are not two ways of saying one thing. They are opposites.

The four that reverse your meaning

hard / hardly

Students who hardly study get better results.
Students who study hard get better results.
Hardly means almost not. The wrong version claims that lazy students do better, which nobody would ever notice you did not mean, because it is a perfectly normal sentence.

late / lately

Lately trains cost more than they used to.
Train fares have risen lately. Arriving late costs you the meeting.
Late is about time of arrival. Lately means in recent weeks. Lately usually sits with a present perfect, which is a useful signal that you have picked the right one.

near / nearly

The school is nearly my house.
The school is near my house, and it is nearly full.
Near is a place. Nearly is an amount, meaning almost. Nearly is also very useful in Task 1, where nearly half and just under a third are exactly the phrases you need.

most / mostly

Mostly students in the survey chose the cheaper option.
Most students chose the cheaper option, mostly because of the price.
Most counts. Mostly explains. If a number could replace the word, it is most. If you are giving the main reason, it is mostly.

The four worth stealing for your writing

1
highly
very, but only with certain words
Example: Highly effective, highly skilled, highly unlikely, highly recommended.
2
deeply
strongly, for feelings and divisions
Example: Deeply concerned, deeply divided, deeply rooted.
3
widely
across many people or places
Example: Widely available, widely used, widely believed.
4
freely
without limits, not without cost
Example: Information moves freely online, but it is not always free.

How to keep them straight

If you could swap the word for almost, it is the -ly one: hardly, nearly.
If you could swap it for very, it is also the -ly one: highly, deeply, widely.
If the word points at a place or a time, it is the short form: hard, late, near, deep, high.
Highly, deeply and widely only fit certain partners. Learn the phrase, not the word.

One of these groups is a risk, the other is a gift

The first four are traps. They produce a normal sentence that reports something you never claimed, and no amount of careful re-reading will catch it, because you know what you meant. The last four are the opposite: highly effective, deeply divided and widely available are the small phrases that make an essay sound like someone who reads English rather than someone who studied it. Learning both halves takes about ten minutes.

More words that behave badly: I am boring: the -ed and -ing mix-up and affect or effect, and 9 other pairs.
